Commentaries:
The Israelites were to redeem or "buy back" the firstborn of their children by offering a lamb in its place. These firstborn children represent the people of God's church today. The redeeming lamb represents Jesus Christ.

The word redeem means "buy back." If a family's firstborn donkey was critical to their livelihood, they could buy it back from God by offering a lamb in its place. Of course, God did not demand that His people offer their firstborn children as literal human sacrifices. They, too, were to be bought back by means of a lamb sacrifice.
