R. Yossi says (Psalms 8:3) "From the mouths of olelim and yonkim You have founded strength. "olelim" — infants in their mothers' womb, as in (Iyyov 3:16) "Why was I not like a buried stillbirth, like olelim who never saw the light"? "yonkim" — those who seek their mothers' breasts, as in (Joel 2:16) "Gather olelim and suckers ("yonkei") of the breasts."
