Jamieson, Fausset & Brown, on Lam 2:17

“Ain. The Lord hath done that which he purposed, he hath fulfilled his word, which he commanded in the days of old: he hath destroyed, and hath not spared, and he hath caused the enemy to rejoice over thee, and hath set up the horn of thy adversaries.”

“Lord--Let not the foe exult as if it was their doing. It was "the Lord" who thus fulfilled the threats uttered by His prophets for the guilt of Judea (Lev 26:16-25; Deu 28:36-48, Deu 28:53; Jer 19:9).”
