'Supplication to the Lord' in the Bible

Then Moses said, “Behold, I am going out from you, and I shall make supplication to the Lord that the swarms of flies may depart from Pharaoh, from his servants, and from his people tomorrow; only do not let Pharaoh deal deceitfully again in not letting the people go to sacrifice to the Lord.”

So Moses went out from Pharaoh and made supplication to the Lord.

Make supplication to the Lord, for there has been enough of God’s thunder and hail; and I will let you go, and you shall stay no longer.”

Now therefore, please forgive my sin only this once, and make supplication to the Lord your God, that He would only remove this death from me.”

He went out from Pharaoh and made supplication to the Lord.
