'Ago' in the Bible

Jerusalem remembers the days of her misery and wanderings, all her treasures that were from the days of long ago. When her people fell into [the] hand of the enemy, there was no one helping her; the enemies saw her, they mocked at her destruction.

The LORD did what he planned. He carried out his threat. Just as he commanded long ago, he has torn down without pity; He let the enemy boast about you and has exalted the power of your enemies.

He has made me reside in deepest darkness like those who died long ago.
