Matthew Henry Presbyterian @wholebiblehenry

Care is here taken to perpetuate the remembrance, I. Of the preservation of Israel's firstborn, when the firstborn of the Egyptians were slain. In memory of that distinguishing favour, and in gratitude for it, the firstborn, in all ages, were to be consecrated to God, as his peculiars (Exo 13:2), and to be redeemed, Exo 13:13.
