John Calvin on Lamentations 1:13

The Prophet proceeds with the same subject, that God’s vengeance had raged most dreadfully agsinst Jerusalem. But employing a metaphor she says, that fire had been sent to her bones. They who interpret bones of fortified places, weaken the meaning of the Prophet. I take bones in their proper sense, ss though it was said, that God’s fire had penetrated into the inmost parts. This way of speaking often occurs in Scripture. By bones is denoted strength or valor. Hence David sometimes deplored, that his bones were vexed or troubled. (Psalm 6:2.) And Hezekiah said in his song

“As a lion he hath broken my bones.” (Isaiah 37:13.)

In the same sense the Prophet now says, that fire had been sent by God, which ruled in his bones, that is, which not only burnt the skin and the flesh, but also consumed the bones. רדה, rede, means also to take away or to receive: but as the former rendering is most commonly taken, I am disposed to follow it — that fire ruled in his bones

There is another similitude added, that God had spread a net before her feet; and thus he had taken away every means of escape. She intimates (for it is Jerusalem who speaks) that she had been ensnared by God’s judgments, so that she was bound over to ruin, as though she had fallen into toils or snares. It is stated in the third place, that she was desolate all the day, so that she sorrowed perpetually. By all the day is meant continually. It is then said, that she sorrowed without end, beyond measure, because she had been turned back by the nets of God, and her bones had been consumed by celestial fire: for the expression from above, ממרום, memerumn, is emphatical, for the Prophet means that it was no common or human burning; because what is ascribed to God exceeds what is human or earthly. It is, then, as though he had said, that it had been such a vengeance as betokened the dreadful power of God; for it was the same as though God had thundered from heaven. We now perceive the import of the words. It follows, —

Lamentations 1:14

14. The yoke of my transgressions is bound by his hand: they are wreathed, and come up upon my neck: he hath made my strength to fall, the Lord hath delivered me into their hands, from whom I am not able to rise up.

14. Ligatumest (hic vertit Hieronymus, vigilavit, namhallucinatus est inpuncto duntaxat צנשקד et legendum est צנשקד quia est punctum sinistrum, quod significat ligave, ligatum est igitur) jugum iniquitatum mearum in manu ejus; implicitae sunt (vel, perplexae,) ascenderunt super collum meum; corruere fecit (vel, debilitavit) robur meum; dedit me Dominus in manus eorum (est in regimine, et tamen nulla sequitur additio, quae respondeat, sed apparet aliquid esse subaudiendum, in manus ergo hostium) ex quibus non potero surgere.
