'Lambs' in the Bible

And Abel gave an offering of the young lambs of his flock and of their fat. And the Lord was pleased with Abel's offering;

And Abraham put seven young lambs of the flock on one side by themselves.

Then Abimelech said, What are these seven lambs which you have put on one side?

And he said, Take these seven lambs from me as a witness that I have made this water-hole.

These lambs Jacob kept separate; and he put his flock in a place by themselves and not with Laban's flock.
