This is one of Hebrew's plain words for nearness. It marks a thing or person as positioned at the immediate side of something else, close enough to be touching or all but touching. It is the word for the cows standing beside the other cows on the riverbank, for a vineyard that lies beside the king's palace, for a chest set beside the altar.
It is a tighter, more physical word than the looser "near" or "around." It does not mean merely in the same region; it means right alongside. When it points at a person rather than a place, the same closeness carries a relational warmth: to lie beside someone, to stand at someone's side, to be the companion always at hand. Wisdom says she was beside God as he made the world, meaning constantly at his side.
From this physical closeness comes a natural extended use: something left or kept beside a person can mean something left in that person's care or possession, simply because what is at your side is what is in your charge. The word itself never stops meaning "alongside"; the sense of keeping is something the surrounding sentence supplies.
Means on every side, encircling a thing completely rather than touching it at one pointPsa 125:22Ki 6:17Exo 19:12
Used for things ranged all the way round a structure or region, such as walls, borders, or surrounding nationsEzk 40:5Num 35:2Jer 1:15

Stays strictly physical: it places one thing right next to another and means nothing else. It can stand alone as next to him in a list of who built which stretch of wall.Neh 3:23Gen 39:10Ezk 1:15
Both
Both can mark plain physical nearness, placing a person or thing right beside another. English translates each as beside or by.1Ki 1:9Luk 5:1Luk 8:5
Reaches well past location to mark a source: something coming from a person's side, that is, from them. The Hebrew word never does this; it only ever points to a physical spot.Jhn 1:6Jhn 16:27Jas 1:5
Also carries a comparing force, setting one thing over against another to say more than, beyond, or rather than. The Hebrew word has no such use.Heb 1:4Luk 13:2Rom 1:25
What scholars say about etsel
The standard lexica treat אֵצֶל as a single locative preposition derived from a noun of side or proximity, glossed "beside, by, near, at the side of" (BDB; HALOT, s.v.). The form is the construct of a segholate noun meaning "side, nearness," used almost exclusively in adverbial-prepositional function with a following genitive or a pronominal suffix; an independent free-standing nominal use is marginal at best. Both BDB and HALOT note the secondary, context-driven nuance "in the possession or keeping of" (e.g. Genesis 39, where Joseph's garment is left beside Potiphar's wife), but treat it as a contextual extension of the spatial sense rather than a distinct meaning. No live disagreement attaches to the word's denotation.
