Genesis 3:22 - 3:24
22 Then Yahweh God said, “Behold, the man has become like one of Us to know good and evil; and now, lest he send forth his hand and take also from the tree of life and eat and live forever”— 23 therefore Yahweh God sent him out from the garden of Eden, to cultivate the ground from which he was taken. 24 So He drove the man out; and at the east of the garden of Eden He stationed the cherubim and the flaming sword which turned every direction to guard the way to the tree of life.
