פּירוש אויף איכה 4:3

Even the serpent. Even though it is cruel, it bares its breast. When it sees its offspring coming from afar, hungry, it uncovers its breasts from their sheath, for it has a cover over its breasts, and it takes them out so that its offspring should not see them covered up and turn away. Then they suckle their young.

Yet the daughters of my people have become brutal. They see their children crying for bread, and yet no one breaks [bread] for them; for their own lives come before their children’s lives because of the hunger.

“Also” [4:3]. Jeremiah says, even a snake whose breast is covered by its skin and is pitiless, yet when their children come, they take out their breast to nurse the children. However, the people of Israel are pitiless, like the ostriches in the wilderness. They do not give food to their children who are hungry. They say: we must feed ourselves first. Our lives come first and with that, the children must die.²³Rashi, Lamentations, 4:3.
