For a similar reason did Israel's exodus from Egypt take place in the noon hour, for, had they departed at night, the Egyptians would have said: "They were able to do this in the darkness of the night because we knew nothing of it. Had we known, we should not have permitted them to depart, but should have compelled them by force of arms to stay in Egypt." God therefore said: "I shall lead out Israel to the noon hour. Let him who wishes to prevent it try to do so."
Noah, too, entered the ark at the noon hour for a similar reason. God said: "If Noah enters the ark at night, his generation will declare: 'He could do so because we were not aware of it, or we should not have permitted him to enter the ark alone, but should have taken our hammers and axes, and crushed the ark.' Therefore," said God, "do I wish him to enter the ark at the noon hour. Let him who wishes to prevent it try to do so."
