ADAM'S PENITENCE "So he drove out the man" (Gen. 3:24). Driving out (i.e.) and he went forth outside the garden of Eden (and he abode) on Mount Moriah, for the gate of the garden of Eden is nigh unto Mount Moriah. Thence He took him and thither He made him return to the place whence he was taken, as it is said, "To till the ground from whence he was taken" (Gen. 3:23).
