The Psalmist's sorrow had culminated, not in the fact that the ungodly prospered, but that God had arranged it so- had it happened by mere chance, he would have wondered, but could not have complained- but how the arranger of all things could so dispense his temporal favours, was the vexatious question. Here, to meet the case, he sees that the divine hand purposely placed these men in prosperous and eminent circumstances, not with the intent to bless them but the very reverse. Surely thou didst set them in slippery places.
