to fall down at someone's feet: to go to the ground in front of a person, out of fear, gratitude, or urgent need
TranslatabilityApproximateCertaintySettled
The picture is physical and immediate. Someone realizes who they are dealing with, and their legs go out from under them in front of him. Every use of this kind comes at a moment of recognition, and the person on the ground almost always speaks straight afterward.
This is not the word for worship. The New Testament has one of those (προσκυνέω), and it names the honor being paid. This word names only what the body does: going down in front of someone and landing at their feet. In the world of the first century that was ordinary behavior for anyone bringing an urgent request to a person with power, so the gesture by itself does not claim that the person receiving it is divine. What gives these scenes their weight is who is on the receiving end and what gets said next.
It is built from the plain verb for falling (πίπτω) with a prefix meaning "toward," and that prefix does real work. This is not stumbling or collapsing where you happen to be standing. It is going down in front of a particular person, on purpose and facing him.

TranslatabilityApproximateCertaintyStrong
Here the subject is weather rather than a person. In the story of the two builders, the rain comes down, the rivers rise, and the winds hit the house that was built on rock.
Greek writers used this verb for anything that strikes a surface hard, from a storm hitting a wall to a sound striking the ear. Matthew's choice also sets up a quiet play on words that English cannot keep: the storm falls on the house, and the house does not fall. Both halves of that sentence run on the same root, so the Greek answers its own question before the reader gets to the next verse.

It reports the plain physical event of a body dropping at someone's feet, and the force behind it is often fear or panic rather than devotion. A trembling woman falls after being found out, Peter falls and asks Jesus to go away from him, and a jailer falls shaking after an earthquake.Mrk 5:33Luk 5:8Luk 8:47Act 16:29
It is not limited to people at all. Wind and water can do it too, so the storm in the parable is described as beating against the house that is built on rock.Mat 7:25
Both
Both describe a parent going down in front of Jesus to plead for a sick child, and the two Gospel scenes are told the same way with different verbs.Mat 9:18Mrk 7:25
Both describe a tormented person or the spirit in him going to the ground before Jesus and blurting out who he is, so in these encounter scenes the two words overlap almost completely.Mrk 5:6Mrk 3:11Luk 8:28
It is the standard word for reverence offered to something as divine, which is why it can be demanded, refused, or misdirected. Satan asks for it and Jesus answers that it belongs to God alone, an angel refuses it, and the beast receives it from the whole earth.Mat 4:9Mat 4:10Rev 13:4Rev 19:10
It can name a whole way of relating to God with no bodily posture in view at all. Jesus and the Samaritan woman argue about where and how people do this, and the answer is about spirit and truth rather than about kneeling or a place.Jhn 4:21Jhn 4:23Jhn 4:24
It covers honor given to an object or figure that is not physically present to be fallen in front of, such as carved images, demons, or the emblem of a hostile power.Act 7:43Rev 9:20Rev 13:15
It also covers the deep bow a person makes to a human superior as a social gesture, where nothing religious is at stake. A debtor drops before his master to beg for time, and a mother approaches Jesus this way before making a request for her sons.Mat 18:26Mat 20:20

It can be used of weather driving against a building, the winds beating on a house until it stands or falls.Mat 7:25
Both
Both describe a whole body going down onto or in front of another person at an emotionally charged moment, so English renders each of them "fell on" or "fell down before".Luk 15:20Act 20:10Luk 5:8Mrk 7:25
Neither word needs a person as the thing that falls: with both, a force can be the subject, whether dread coming over a man or wind driving at a house.Luk 1:12Mat 7:25
Both belong to scenes of sudden encounter with power, where someone meets God or his messenger and the meeting knocks the person off balance.Act 19:17Luk 8:28
It is the word Acts uses for the Holy Spirit coming down on people, arriving on them from above rather than being approached by them.Act 8:16Act 10:44Act 11:15
It describes something felt rather than seen settling over people from outside them, most often fear coming over a whole crowd at once, and once the insults aimed at God landing on the one who serves him.Luk 1:12Act 19:17Rev 11:11Rom 15:3
It covers the warm embrace in which one person throws himself on another's neck, in welcome home or in a tearful farewell.Luk 15:20Act 20:37
It can picture a crowd surging in and pressing bodily against a person, everyone straining to reach him at once.Mrk 3:10
γονυπετέωto go down on the knees in front of someone, naming the knees rather than the whole body reaching the ground
It names no part of the body. It only says that someone drops toward something, so when the knees or the feet matter the sentence has to spell them out separately.Luk 5:8Mrk 7:25
Because it means no more than falling against something, it works for things as well as for people: in the storm picture the flooded rivers are what come crashing against the house.Mat 7:25
Again and again the drop is what fear does to a person. The healed woman comes shaking, and the jailer is trembling when he goes down in front of Paul and Silas.Mrk 5:33Luk 8:47Act 16:29
It also covers a forced acknowledgment rather than a willing one. Unclean spirits go down in front of Jesus and shout out who he is, against their own interest.Mrk 3:11Luk 8:28
Both
Both describe someone going down in front of another person as the opening of a plea, with the actual request spoken in the very next breath.Mrk 1:40Mrk 7:25
Both put the one on the ground below the one standing, marking that person as holding power the other does not have.Mat 17:14Luk 8:28
This word has the knee built into it, so it says exactly which part of the body moves. The person bends the knee, and can keep walking up and talking while doing it, which makes it a chosen posture rather than a fall.Mat 17:14Mrk 10:17
It is the word that can carry a staged, insincere show of respect. The soldiers go down on the knee in front of Jesus as part of the mockery, along with the thorn crown and the fake royal greeting.Mat 27:29
In all four New Testament uses the knee is bent to Jesus and to no one else, so the gesture belongs to scenes where someone is being treated as a healer or a king.Mrk 1:40Mat 27:29
prospiptō in the other biblical languages
נָפַלHebrew“to fall: fall”the Hebrew verb for falling, which needs a phrase like "on his face" added to it to describe this same gesture
The Greek word carries the idea of moving hard against a target, so it can describe weather instead of people: in the parable the rain, the floods, and the winds hurl themselves at the house and beat against it. The picture is force driving into something, not a body sinking to the ground.Mat 7:25
Every use involving a person or a spirit happens in front of Jesus or his messengers, and it happens the moment they see him: unclean spirits go down before him and shout who he is, a fisherman drops at his knees, a jailer falls shaking. The word marks a reaction to a presence rather than a turn in someone's circumstances.Mrk 3:11Luk 8:28Luk 5:8Act 16:29
Both
Both words name a living person going all the way to the ground in front of someone greater. Abram drops on his face before God and the people go down when fire comes out from the LORD; the Greek word does the same work when Peter goes down at Jesus' knees.Gen 17:3Lev 9:24Luk 5:8
Both cover the fall that opens a request. Joseph's brothers go down in front of him and then plead for their lives, and a mother goes down at Jesus' feet and asks him to free her daughter. New Testament writers use the Greek word in exactly the settings where the Hebrew word is rendered "fell before" someone.Gen 44:14Gen 50:18Mrk 7:25
The Hebrew word is the ordinary way to say that someone died in battle. To fall by the sword is simply to be killed, and whole armies and a whole generation fall this way.Lev 26:7Exo 32:28Num 14:29
It also covers plain physical drops with nobody bowing at all: kings tumbling into tar pits as they flee, an ox dropping into an uncovered pit, a dead creature landing inside a clay pot.Gen 14:10Exo 21:33Lev 11:33
It is the word for something arriving on a person from outside their control. A deep sleep, a horror of darkness, or dread of an approaching army falls on people, and a person's face falls when anger takes hold.Gen 2:21Gen 15:12Exo 15:16Gen 4:5
What scholars say about prospiptō
BDAG divides προσπίπτω into two senses: (1) to fall down before someone, prostrate oneself at someone's feet, covering the seven Synoptic and Acts instances; and (2) to strike against, beat against, with Matthew 7:25 as the only New Testament instance. LSJ documents the same range across classical and Hellenistic Greek, where the compound serves both for falling at the knees of a superior in supplication and for physical forces striking an object, including sounds and reports reaching the senses. Michaelis, in the TDNT article on πίπτω and its compounds, treats προσπίπτω as part of the Synoptic vocabulary of approach to Jesus, standing alongside but not identical with προσκυνέω: the Evangelists use it for the bodily act of prostration without the cultic freight the latter can carry. EDNT notes the concentration of the verb in Mark and Luke, where it repeatedly marks the response of those who have just perceived Jesus' identity or power, including the acclamations of unclean spirits in Mark 3:11 and Luke 8:28.
