Which was part of the OT covenant, in which male infants were made a part of due to their Jewish parentage and that ceremony. It did not mean they were redeemed. The OT covenant was replaced by 'a better covenant', Heb. 7:22, which was predicted in the OT. In one of his final addresses to the nation of Israel, Moses looks forward to a time when Israel would be given “a heart to understand” (
Deuteronomy 29:4, ESV). Infants have no such understanding. The prophet Jeremiah also predicted the New Covenant. “‘The day will come,’ says the Lord, ‘when I will make a new covenant with the people of Israel and Judah. . . . But this is the new covenant I will make with the people of Israel on that day,’ says the Lord. ‘I will put my law in their minds, and I will write them on their hearts. I will be their God, and they will be my people’” (
Jeremiah 31:31,
33). Entering the New Covenant is made possible only by faith in Christ, who shed His blood to take away the sins of the world (
John 1:29). The New Covenant is also mentioned in
Ezekiel 36:26–27, “I will give you a new heart and put a new spirit in you; I will remove from you your heart of stone and give you a heart of flesh. And I will put my Spirit in you and move you to follow my decrees and be careful to keep my laws.”
I was referring to the fact that very few US households have a person younger than 3, let alone an infant of a few weeks.
Wouldn't you sort of have to be an adult to understand and obey that command?
