We may picture a man digging a pit, with the loose soil giving way as he digs, thus trapping him in it himself in place of the wild animal that he hoped to catch. Sin confuses the sinner. Evil is a boomerang. A striking OT example of this principle is found in the life of Haman (see Esther 5-7; Prov. 26:27; Eccl. 10:8).
