Exodus 13:13

13 A firstborn donkey may be bought back from the LORD by presenting a lamb or young goat in its place. But if you do not buy it back, you must break its neck. However, you must buy back every firstborn son.

Exodus 13:13 Meaning and Commentary

Exodus 13:13

And every firstling of an ass thou shalt redeem with a lamb,
&c.] Which was given to the priest for it; and according to the Jewish canon F6, it might be redeemed with that only;

``not with a calf, nor with an animal (a goat or a ram, as Bartenora interprets it), nor with a lamb slain, or torn to pieces.''
Jarchi thinks the ass only was to be redeemed, and not the firstling of any other unclean creature, but his reasons are insufficient; all unclean creatures, as horses, camels, dogs, swine are included in it, as should seem from ( Numbers 18:15 ) and this is the rather particularly mentioned, because there was a greater plenty of them than of horses and camels, and because they were very useful creatures; and if these were to be redeemed, then much more those of less value, and less useful. Hence might arise the story and calumny, as some have thought, of the Jews worshipping an ass's head: and if thou wilt not redeem it, then thou shall break its neck;
cut off its head on the back of the neck with a knife or cleaver, such as butchers use, as the Misnah F7, and its commentators, interpret it, so that the owner should have no profit by it: and all the firstborn of man amongst thy children shall thou redeem;
with the price of five shekels of the sanctuary, and within thirty days of the birth of it, ( Numbers 18:16 ) and these being to be redeemed as the unclean beasts were, shows that men are by nature unclean, and even the firstborn, whose names are written in heaven, the elect of God, and need redemption by the blood of the Lamb.

Exodus 13:13 In-Context

11 “This is what you must do when the LORD fulfills the promise he swore to you and to your ancestors. When he gives you the land where the Canaanites now live,
12 you must present all firstborn sons and firstborn male animals to the LORD, for they belong to him.
13 A firstborn donkey may be bought back from the LORD by presenting a lamb or young goat in its place. But if you do not buy it back, you must break its neck. However, you must buy back every firstborn son.
14 “And in the future, your children will ask you, ‘What does all this mean?’ Then you will tell them, ‘With the power of his mighty hand, the LORD brought us out of Egypt, the place of our slavery.
15 Pharaoh stubbornly refused to let us go, so the LORD killed all the firstborn males throughout the land of Egypt, both people and animals. That is why I now sacrifice all the firstborn males to the LORD —except that the firstborn sons are always bought back.’
