Intimidated by this affliction, Pharaoh permitted the people to go, the little ones as well as the men and the women, only he asked that they let their flocks and their herds be stayed. But Moses said: "As thou livest, our cattle also shall go with us. Yea, if but the hoof of an animal belongs to an Israelite, the beast shall not be left behind in Egypt." This speech exasperated Pharaoh to such a degree that he threatened Moses with death in the day he should see his face again.
At this very moment the Lord appeared unto Moses, and bade him inform Pharaoh of the infliction of the last plague, the slaying of the first-born. It was the first and the last time that God revealed Himself in the royal palace. He chose the residence of Pharaoh on this occasion that Moses might not be branded as a liar, for he had replied to Pharaoh's threat of killing him if he saw his face again, with the words, "Thou hast spoken well; I will see thy face again no more."
