Amos 2:9

Yet destroyed I the Amorite before them, when Joshua overthrew them in battle. Numbers 21:24; Deuteronomy 2:31, whose height was like the height of the cedars, and he was strong as the oaks, a powerful people; yet I destroyed his fruit from above and his roots from beneath, the picture of a mighty tree being retained to make the fact of his annihilation more vivid.
