Exodus 10:3-10

So Moses and Aaron came in to Pharaoh and said to him, “Thus says the LORD God of the Hebrews: ‘How long will you refuse to humble yourself before Me? Let My people go, that they may serve Me. Or else, if you refuse to let My people go, behold, tomorrow I will bring locusts into your territory. And they shall cover the face of the earth, so that no one will be able to see the earth; and they shall eat the residue of what is left, which remains to you from the hail, and they shall eat every tree which grows up for you out of the field. They shall fill your houses, the houses of all your servants, and the houses of all the Egyptians—which neither your fathers nor your fathers’ fathers have seen, since the day that they were on the earth to this day.’ ” And he turned and went out from Pharaoh. Then Pharaoh’s servants said to him, “How long shall this man be a snare to us? Let the men go, that they may serve the LORD their God. Do you not yet know that Egypt is destroyed?” So Moses and Aaron were brought again to Pharaoh, and he said to them, “Go, serve the LORD your God. Who are the ones that are going?” And Moses said, “We will go with our young and our old; with our sons and our daughters, with our flocks and our herds we will go, for we must hold a feast to the LORD.” Then he said to them, “The LORD had better be with you when I let you and your little ones go! Beware, for evil is ahead of you.
