Psalm 35:21 New English Translation

²¹They are ready to devour me;^[a]
they say, “Aha! Aha! We’ve got you!”^[b]

Psalm 35:21 tn Heb “and they cause their mouth to be wide against me.” The prefixed verbal form with vav (ו) consecutive here carries on the generalizing mood of the previous verse. For other examples of this use of the prefixed verbal form with vav consecutive, see GKC 329 §111.t.
Psalm 35:21 tn Heb “our eye sees.” Apparently this is an idiom meaning to “look in triumph” or “gloat over” (see Ps 54:7).
