Ibn Ezra, on Isa 49:15

“Can a woman forget her infant, so as not to have pity on the son of her womb? and if she should forget, yet will not I forget thee.”

“Can a woman, etc. This is mentioned, because God has given to woman a natural disposition to have pity on her children. עולל═עול Sucking child. Comp. Jer. 6:11; Is. 65:20. That she should not have compassion, etc. Repetition of the same idea. גם אלח תשכחנה Yea, they may forget. There are cruel women, that forget their children or themselves; or there are women that forget these, yet will I not forget thee. Her sucking child is mentioned, because the mother has usually more compassion for the little one that has no strength.”
