Psalm 34:2 New English Translation

²I will boast^[a] in the Lord;
let the oppressed hear and rejoice.^[b]

Psalm 34:2 tn Heb “my soul will boast”; or better, “let my soul boast.” Following the cohortative form in v. 1, it is likely that the prefixed verbal form here is jussive.
Psalm 34:2 tn The two prefixed verbal forms in this verse are best taken as jussives, for the psalmist is calling his audience to worship (see v. 3).
