'Lambs' in the Bible

And Abraham set seven ewe lambs of the flock by themselves.

And Abimelech said unto Abraham, What mean these seven ewe lambs which thou hast set by themselves?

And he said, These seven ewe lambs shalt thou take of my hand, that it may be a witness unto me, that I have digged this well.

And Jacob separated the lambs, and set the faces of the flocks toward the ringstreaked and all the black in the flock of Laban: and he put his own droves apart, and put them not unto Laban's flock.
