C. F. Keil and Franz Delitzsch on Lamentations 4:10

Lam 4:10

Still more horrible was the misery of the women. In order to keep themselves from dying of hunger, mothers boiled their children for food to themselves; cf. Lam 2:20. By the predicate "compassionate," applied to hands, the contrast between this conduct and the nature, or the innate love, of mothers to their children, is made particularly prominent. בּרות is a noun = בּרוּת, Psa 69:22. On "the destruction of the daughter of my people," cf. Lam 2:11.
