the fear a mighty figure inspires in others, and so also the one who is feared or the deed that produces the fear
Hebrew has several words for fear, and this one usually looks at fear from the outside. Its close relative, the word behind the phrase "the fear of the LORD" (יִרְאָה), names what a person feels, the fright or the reverence inside them. This word more often names the fear that comes off someone strong: the dread of human beings that falls on the animals after the flood, the panic that spreads through a country ahead of an advancing army. That one starting point explains everything else the word does.
Once fear is thought of as something a powerful figure gives off, it is a short step to naming the figure himself. Isaiah tells Judah not to be afraid of what everyone around them is afraid of, and then says that the LORD of hosts should be their dread instead: God is to be your fear. By the same logic the word can name the respect a master is owed, and Malachi uses it that way when God asks a careless priesthood where the honor due to him has gone.
The same step from fear to the thing that causes it gives the word its most familiar use. Four times, always in the phrase "great terror," it names what God did to bring Israel out of Egypt, and it stands at the end of a fixed series of exodus language: a mighty hand, an outstretched arm, signs and wonders, and great terror. Here the word has traveled the whole distance from feeling to event, because the awe simply is the plagues and the sea.
Because the word is rare, only twelve verses in all, its shade in any one verse is read mostly off the words standing beside it. Next to other terror words, one for sudden panic (פַּחַד) and one for shattering dread (חַת), it means fear pressed down on someone from outside; next to covenant and honor, it means reverence.
Nuances
Whether this word appears in Psalm 9:20 at all. The consonants can be pointed as this noun, "terror," or as an unrelated noun meaning "teacher, lawgiver," and BDB records both readings while judging that neither is altogether satisfactory. Modern scholarship remains divided.
- contested"Terror": "Set terror over them, O LORD." The Masoretic pointing reads the word this way, Aquila and Jerome follow it, and the parallel line's request that the nations know they are only human fits a prayer for dread.; BDB, A Hebrew and English Lexicon of the Old Testament, s.v. מוֹרָה, on Psalm 9:21 Hebrew (9:20 English), citing the Masora, Aquila, and Jerome; New Revised Standard Version, Psalm 9:20
- contested"Lawgiver": "Appoint a lawgiver over them, O LORD." The Septuagint read the consonants as the word for a teacher or lawgiver and rendered it nomothetes.; Septuagint, Psalm 9:21 (νομοθέτην); R. G. Bratcher and W. D. Reyburn, A Handbook on Psalms (United Bible Societies, 1991), on Psalm 9:20
