'Lambs' in the Bible

I will pass through all thy flock to-day, to remove thence all the speckled and spotted sheep, and all the brown lambs, and the spotted and speckled among the goats; and that shall be my hire.

And my righteousness shall answer for me hereafter, when thou comest about my hire, before thy face: all that is not speckled and spotted among the goats, and brown among the lambs, let that be stolen with me.

And he removed that day the he-goats that were ringstraked and spotted, and all the she-goats that were speckled and spotted, every one that had white in it, and all the brown among the lambs, and gave them into the hand of his sons.

And Jacob separated the lambs, and set the faces of the flock toward the ringstraked, and all the brown in the flock of Laban; and he made himself separate flocks, and did not put them with Laban's flock.
