John Calvin Commentary Lamentations 3:61

"Thou hast heard their reproach, O Jehovah, and all their devices against me," — Lamentations 3:61 (ASV)

We see that this is a repetition, but regarding vengeances, he now mentions reproaches. And in this way, he again sought to turn God to mercy; for when he brings no aid, he seems to close his eyes and render his ears deaf; but when he attends to our troubles, he then quickly brings help.

The Prophet, then, having said that God saw, now refers to hearing: he had heard their reproaches. Using language that is not strictly literal, the Prophet adds that God had also heard their thoughts; though the Prophet speaks here not only of their secret plans, but also of all the wicked conspiracies by which his enemies had contrived to ruin him.
