Charles H. Spurgeon on Psalms 18:26

"Wilt shew thyself froward." It is a similitude taken from wrestlers, and noteth a writhing of one's self against an adversary. Compare herewith Deuteronomy 32:5. "They are a perverse and a crooked generation," the same two words that are here in this text; the latter importeth that they wriggled and writhed after the manner of wrestlers that wave up and down, and wind the other way, when one thinks to have him here or there. But all will not serve their turn to save them from punishment. God will be sure to meet with them, his Word will lay hold on them, and their sins shall find them out. —John Trapp.
