1. Keeping instruction and covenant obligations · dominant

   In Deuteronomy 33:9, the Qal imperfect plural stands in the clause about keeping God's word and guarding his covenant. The same use appears with testimonies, statutes, precepts, commandments, and instruction: in Psalm 119:2 the APB renders the clause "those who keep his testimonies," while Psalm 119:33 has a first-person imperfect for the speaker's intended response to the way of the statutes.

2. Guarding or preserving someone or something · common

   The verb marks protective care in clauses directed toward a person, life, or route. In Deuteronomy 32:10, the Qal imperfect singular occurs after the wilderness finding and encircling of Israel; in Isaiah 27:3, a participle and first-person imperfect occur in the LORD's continual care for the vineyard, which the APB renders "I will guard her." Proverbs 2:8 likewise places the infinitive construct with the paths of justice and the way of the faithful.

3. Watching as a watchman or observer · occasional

   Active participles identify watchers or frame an act of observation. In Jeremiah 31:6, the masculine plural participle occurs where watchmen call from Ephraim's hill country; Job 7:20 addresses a "watcher of man" in the APB. The plural participle in 2 Kings 17:9 and 2 Kings 18:8 occurs in the phrase extending from the watchmen's tower to the fortified city.

4. Being guarded, preserved, or hidden · rare

   Passive participles describe a resulting guarded or retained condition. Isaiah 49:6 refers to "the preserved of Israel" in the APB, while Isaiah 48:6 places a feminine plural passive participle in the clause about hidden things not previously known. Ezekiel 6:12 also uses a passive participle for one remaining and watched before famine.

   Ezekiel 6:12Isaiah 48:6Isaiah 49:6Isaiah 1:8Proverbs 7:10

In the Anselm Project Bible: The APB variously presents the clauses with "keep," "guard," "watch," "watch over," "preserved," and "hidden." Because its English is a whole-verse translation, these renderings show the verse contexts but do not assign each English word mechanically to the Hebrew form.
