Keil & Delitzsch, on Lam 2:16

“Phe. All thy enemies have opened their mouth against thee: they have hissed, and gnashed with the teeth, and have said: We will swallow her up: lo, this is the day which we looked for: we have found it, we have seen it.”

“The enemy in triumph express their joy over the fall of Jerusalem. The opening of the mouth (as in Psa 35:21; Job 16:10), taken in connection with what follows, is also a gesture peculiar to scornful speech. The gnashing of the teeth (Psa 35:16; Psa 37:12; Job 16:9) is here an expression of rage that has burst out. The object of "we have swallowed" is to be derived from the context ("against thee"), viz., the city of Jerusalem. Surely this" is a strong asseveration - "this is the very day." The asyndetic collection of the three verbs accords with the impassioned character of the enemy's speech. "To see" is here equivalent to living to see.”
