“He said to them: So let the Lord be with you, when I will let you and your children go; see that evil is facing you” (Exodus 10:10). “Pharaoh's servants said.… Moses and Aaron were returned.… Moses said: We will go with our young and with our old.… He said to them: So let the Lord be with you…” (Exodus 10:7–10) – what is “evil facing you”? He said to them: ‘It is the way of youths and elders to sacrifice, but the young and the children?
One who says this, his intention is only to flee, not as you are saying: “A three-day journey” (Exodus 5:3, 8:23). Therefore, see that what you are thinking, that you intend to flee, will return against you, so you will not depart from here.’ “Not so; let the men go now and serve the Lord; for that is what you seek. He drove them out from Pharaoh's presence” (Exodus 10:11).
That is what is written: “Let the men go now” – he said to him: ‘If you say: Our intent is not to flee, prove your assertion: “Let the men go now.” Since the children are not fit to serve, why do you need them? Rather, “for that is what you seek” – you are seeking to perform evil, you wish to flee. Therefore, I will not listen to you at all.’
Immediately, he issued a command and drove them from there; that is what is written: “He drove them out from Pharaoh's presence.”
