'Dust of the Ground' in the Bible

then the Lord God formed [that is, created the body of] man from the dust of the ground, and breathed into his nostrils the breath of life; and the man became a living being [an individual complete in body and spirit].

Then the Lord said to Moses, “Say to Aaron, ‘Stretch out your staff and strike the dust of the ground, and it will become [biting] gnats (lice) throughout the land of Egypt.’”
