Then Pharaoh’s servants said to him, “How long shall this man be a snare to us? Let the men go, that they may serve the Lord their God. Do you not yet understand that Egypt is ruined?” So Moses and Aaron were brought back to Pharaoh. And he said to them, “Go, serve the LORD your God. But which ones are to go?” Moses said, “Only the adults will go, for we are holding a special feast to the LORD in which our young are not permitted to eat. We will leave our sons and daughters here in Egypt with you.”
Would it have ever occured to the Restoration generation to stop circumcising their boys and allowing their children to participate in the Feasts based on their readings of Jer 31 (“all shall know me”)?
