Moses and Aaron caused the land to be full of gnats

16 Then Yahweh said to Moses/me, “Tell Aaron to strike the ground with his stick. When he does that, all the fine particles of ground/dust will become gnats, all over the land of Egypt.” 17 So they/we did that. Aaron struck the ground with his stick, and all over Egypt, the fine particles of ground/dirt became gnats. The gnats covered the people and all their animals. 18 The men who worked magic tried to cause gnats to appear, but they were unable to do it. So the gnats stayed on the Egyptian people and on their animals. 19 The men who worked magic said to the king, “It is God who has done this with his power [MTY]!” But the king continued to be stubborn [IDM], and he would not pay attention to us, just as Yahweh had predicted.
