John Wesley on 2 Chronicles 28:20

Distressed - Or, straitened him, by robbing him of his treasures. Strengthened not - A most emphatical expression: for tho' he weakened his present enemy the Syrian, yet all things considered, he did not strengthen Ahaz and his kingdom, but weaken them; for by removing the Syrian, who, tho' a troublesome neighbour, was a kind of bulwark to him, he smoothed the way for himself, a far more dangerous enemy, as appears in the very next king's reign.
