'Sucked' in the Bible

Oh that thou wert as my brother, That sucked the breasts of my mother! Should I find thee without, I would kiss thee; And they would not despise me.

And it came to pass as he spake these things, a certain woman, lifting up her voice out of the crowd, said to him, Blessed is the womb that has borne thee, and the paps which thou hast sucked.
