John Wesley on Exodus 10:10

Let the Lord be so with you, as I will let you go, and your little ones - He now curses and threatens them, in case they offered to remove their little ones, telling them it was at their peril. Satan doth all he can to hinder those that serve God themselves, from bringing their children in to serve him. He is a sworn enemy to early piety, knowing how destructive it is to the interests of his kingdom.
