Rules for Firstborn Animals

Leviticus 27:26-27

`Only, a firstling which is Jehovah's firstling among beasts--no man doth sanctify it, whether ox or sheep; it is Jehovah's.

And if among the unclean beasts, then he hath ransomed it at thy valuation, and he hath added its fifth to it; and if it is not redeemed, then it hath been sold at thy valuation.
