'Flies' in the Bible

Else, if thou wilt not let my people go, behold, I will send swarms of flies upon thee, and upon they servants, and upon thy people, and into thy houses: and the houses of the Egyptians shall be full of swarms of flies, and also the ground whereon they are.

And I will set apart in that day the land of Goshen, in which my people dwell, that no swarms of flies shall be there; to the end thou mayest know that I am Jehovah in the midst of the earth.

And Jehovah did so; and there came grievous swarms of flies into the house of Pharaoh, and into his servants houses: and in all the land of Egypt the land was corrupted by reason of the swarms of flies.

And Moses said, Behold, I go out from thee, and I will entreat Jehovah that the swarms of flies may depart from Pharaoh, from his servants, and from his people, to-morrow: only let not Pharaoh deal deceitfully any more in not letting the people go to sacrifice to Jehovah.

And Jehovah did according to the word of Moses; and he removed the swarms of flies from Pharaoh, from his servants, and from his people; there remained not one.

He sent among them swarms of flies, which devoured them; And frogs, which destroyed them.

He spake, and there came swarms of flies, And lice in all their borders.

Dead flies cause the oil of the perfumer to send forth an evil odor;'so doth a little folly outweigh wisdom and honor.
