until an arrow cleaves open his liver, just as a bird hastens into the trap, and he has not known that it involves his very soul.”​—Proverbs 7:22, 23.

He does not see the danger of it all until “an arrow cleaves open his liver,” that is, until he receives a wound that can cause his death. The death may be physical in that he exposes himself to death-dealing sexually transmitted diseases.b The wound can also cause his spiritual death; “it involves his very soul.” His entire being and his life are seriously affected, and he has gravely sinned against God. He thus hastens into the grip of death like a bird into a trap!
