'Double' in the Bible

And every beast that hath cloven hoofs, and the feet quite split open into double hoofs, and which cheweth the cud, among the beasts, that ye shall eat.

Let it not seem hard unto thee, when thou sendest him away free from thee; for double the worth of a hired servant hath he been to thee, in serving thee six years; and Jehovah thy God will bless thee in all that thou doest.

but he shall acknowledge as firstborn the son of the hated, by giving him a double portion of all that is found with him; for he is the firstfruits of his vigour: the right of the firstborn is his.
