And the sons of Reuben, the firstborn of Israel, shall be their generations, according to their families, according to the house of their fathers, according to the number of names, according to their heads, every male from the son of twenty years and above, all going forth to war.

Every thing cleaving the womb for all flesh, which they shall bring to Jehovah, in man or in cattle, shall be to thee: but redeeming, thou shalt redeem the first-born of man, and the firstborn of unclean cattle thou shalt redeem.
