You must redeem the firstborn of a donkey with a lamb; but if you do not redeem it, you are to break its neck. You must redeem all the firstborn of your sons. No one shall appear before Me empty-handed.
KJV
But the firstling of an ass thou shalt redeem with a lamb: and if thou redeem [him] not, then shalt thou break his neck. All the firstborn of thy sons thou shalt redeem. And none shall appear before me empty.
ASV
And the firstling of an ass thou shalt redeem with a lamb: and if thou wilt not redeem it, then thou shalt break its neck. All the first-born of thy sons thou shalt redeem. And none shall appear before me empty.
