Old Testament

The Book of Exodus:
Chapter 8:20-24-32

And the Lord said to Moses, "Rise early in the morning and stand before Pharaoh as he comes out to the water. Then say to him, 'Thus says the Lord: "Let My people go, that they may serve Me. Or else, if you will not let My people go, behold, I will send swarms of flies on you and your servants, on your people and into your houses. The houses of the Egyptians shall be full of swarms of flies, and also the ground on which they stand. And in that day I will set apart the land of Goshen, in which My people dwell, that no swarms of flies shall be there, in order that you may know that I am the Lord in the midst of the land. I will make a difference between My people and your people. Tomorrow this sign shall be." ' "

And the Lord did so. Thick swarms of flies came into the house of Pharaoh, into his servants' houses, and into all the land of Egypt. The land was corrupted because of the swarms of flies.
Then Pharaoh called for Moses and Aaron, and said, "Go, sacrifice to your God in the land." And Moses said, "It is not right to do so, for we would be sacrificing the abomination of the Egyptians to the Lord our God. If we sacrifice the abomination of the Egyptians before their eyes, then will they not stone us? We will go three days' journey into the wilderness and sacrifice to the Lord our God as He will command us." And Pharaoh said, "I will let you go, that you may sacrifice to the Lord your God in the wilderness; only you shall not go very far away. Intercede for me." Then Moses said, "Indeed I am going out from you, and I will entreat the Lord, that the swarms of flies may depart tomorrow from Pharaoh, from his servants, and from his people. But let Pharaoh not deal deceitfully anymore in not letting the people go to sacrifice to the Lord." So Moses went out from Pharaoh and entreated the Lord. And the Lord did according to the word of Moses; He removed the swarms of flies from Pharaoh, from his servants, and from his people. Not one remained. But Pharaoh hardened his heart at this time also; neither would he let the people go.

New Testament

The Book of Acts: Chapter
28:1-10

Now when they had escaped, they then found out that the island was called Malta. And the natives showed us unusual kindness; for they kindled a fire and made us all welcome, because of the rain that was falling and because of the cold. But when Paul had gathered a bundle of sticks and laid them on the fire, a viper came out because of the heat, and fastened on his hand. So when the natives saw the creature hanging from his hand, they said to one another, "No doubt this man is a murderer, whom, though he has escaped the sea, yet justice does not allow to live." But he shook off the creature into the fire and suffered no harm. However, they were expecting that he would swell up or suddenly fall down dead. But after they had looked for a long time and saw no harm come to him, they changed their minds and said that he was a god. In that region there was an estate of the leading citizen of the island, whose name was Publius, who received us and entertained us courteously for three days. And it happened that the father of Publius lay sick of a fever and dysentery. Paul went in to him and prayed, and he laid his hands on him and healed him. So when this was done, the rest of those on the island who had diseases also came and were healed. They also honored us in many ways; and when we departed, they provided such things as were necessary.
