'Lambs' in the Bible

Then Abraham set apart seven ewe lambs of the flock,

and Abimelech said to Abraham, “What is the meaning of these seven ewe lambs which you have set apart?”

Abraham said, “You are to accept these seven ewe lambs from me as a witness for me, that I dug this well.”

So the flocks mated and conceived by the branches, and the flocks gave birth to streaked, speckled, and spotted offspring.

Jacob separated the lambs, and [as he had done with the peeled branches] he made the flocks face toward the streaked and all the dark or black in the [new] flock of Laban; and he put his own herds apart by themselves and did not put them [where they could breed] with Laban’s flock.
