'Black' in the Bible

I will pass through all thy flock to-day, removing from thence every speckled and spotted one, and every black one among the sheep, and the spotted and speckled among the goats: and of such'shall be my hire.

So shall my righteousness answer for me hereafter, when thou shalt come concerning my hire that is before thee: every one that is not speckled and spotted among the goats, and black among the sheep, that if found with me, shall be counted stolen.

And he removed that day the he-goats that were ringstreaked and spotted, and all the she-goats that were speckled and spotted, every one that had white in it, and all the black ones among the sheep, and gave them into the hand of his sons;

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.
