Êxodo 8:8
One should also observe that the term prayer,which often differs in meaning from "invocation," is here employed in the case of one who promises in a vow to do certain things if God grants him certain other things. But the term is also used in the ordinary way. For example, we found this to be so in Exodus after the description of the plague of the frogs, which was the second of the ten plagues: … "But Pharaoh called Moses and Aaron and said to them: 'Pray to the Lord on my account to take away the frogs from me and my people; and I will let the people go to sacrifice to the Lord.' " When Pharaoh employs the word prayer the habitual meaning of "prayer" is conveyed in addition to the above meaning. If anyone finds this difficult to see, it becomes clear in what follows, namely: "And Moses said to Pharaoh: 'Set me a time when I shall pray for you, and for your servants, and for your people, that the frogs may be driven away from you and from your house and from your people, and may remain only in the river.' "We noted, however, that in the case of the sciniphs, the third plague, Pharaoh does not ask that prayer be made, nor does Moses pray. And in the case of the flies, the fourth plague, he says, "Pray therefore for me to the Lord." And then Moses said, "I will go out from you and will pray to the Lord. And the flies shall depart from Pharaoh, and from his servants, and from his people tomorrow." And a little further on we read: "So Moses went out from Pharaoh and prayed to God." Again in the case of the fifth and also of the sixth plague Pharaoh did not ask that prayer be made, nor did Moses pray. In the seventh plague "Pharaoh sent and called Moses and Aaron, saying to them, 'I have sinned this time. The Lord is just, but I and my people are wicked. Pray to the Lord, that the thunderings of God and the hail and the fire may cease.' " And a little further on we read: "And Moses went from Pharaoh out of the city and stretched forth his hands to the Lord; and the thunders … ceased." We shall discuss more suitably at another time why it is not said as on the previous occasions that "he prayed" but rather that "he stretched forth his hands to the Lord." And in the case of the eighth plague Pharaoh says, "And pray to the Lord your God, that he take away from me this death. And Moses going forth from the presence of Pharaoh, prayed to the Lord." — ON PRAYER 3.2-3
