31:10-18 The king of Egypt resembled the king of Assyria in his greatness: here we see he resembles him in his pride. And he shall resemble him in his fall. His own sin brings his ruin. None of our comforts are ever lost, but what have been a thousand times forfeited. When great men fall, many fall with them, as many have fallen before them. The fall of proud men is for warning to others, to keep them humble. See how low Pharaoh lies; and see what all his pomp and pride are come to. It is best to be a lowly tree of righteousness, yielding fruit to the glory of God, and to the good of men. The wicked man is often seen flourishing like the cedar, and spreading like the green bay tree, but he soon passes away, and his place is no more found. Let us then mark the perfect man, and behold the upright, for the end of that man is peace.

Fairbairn points the Hebrew differently, so as for "their trees," to translate, "(And that none that drink water may stand) on themselves, (because of their greatness)." But the usual reading is better, as Assyria and the confederate states throughout are compared to strong trees. The clause, "All that drink water," marks the ground of the trees' confidence "in their height," namely, that they have ample sources of supply. Maurer, retaining the same Hebrew, translates, "that neither their terebinth trees may stand up in their height, nor all (the other trees) that drink water."
