“My eyes will flow without ceasing, without respite,

John Calvin Reformed @genevareformer

He repeats the same in other words, — that his eyes flowed down with tears. He still retains the singular number, but this is common in Hebrew. He then says, that his eye without end flowed down, so that there was no rest But it afterwards follows — Lamentations 3:50 50. Till the LORD look down, and behold from heaven. 50. Donec aspiciat et videat Jehova e coelis.

Matthew Henry Presbyterian @wholebiblehenry

It is easier to chide ourselves for complaining than to chide ourselves out of it. The prophet had owned that a living man should not complain, as if he checked himself for his complaints in the former part of the chapter; and yet here the clouds return after the rain and the wound bleeds afresh; for great pains must be taken with a troubled spirit to bring it into temper.

Commenting on Lamentations 3:42-54

John Gill Reformed Baptist @doctorgill

Waters flowed over mine head,.... As in a pit or dungeon, where there is not only mire and clay, but much water, into which persons being put, sink, and are covered therewith; see Psa 69:1; this is to be understood metaphorically of the waters of afflictions, which overflowed and overwhelmed the people of the Jews.
