'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.

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

But he shall acknowledge the son of the hated for the firstborn, by giving him a double portion of all that he hath: for he is the beginning of his strength; the right of the firstborn is his.
