Exodus 13:13

You must redeem every firstborn donkey with a lamb, and if you do not redeem it, you are to break its neck. And every firstborn of your sons you must redeem.

And every firstling of an ass thou shalt redeem with a lamb; and if thou wilt not redeem it, then thou shalt break his neck: and all the firstborn of man among thy children shalt thou redeem.
