Hell and destruction are before the LORD: how much more then the hearts of the children of men?
– Proverbs 15:11
The word for hell is sheol and means the unseen place of the dead. It is like the Greek hades. The word for destruction is abaddon and means a place of destruction. It emphasizes the state of suffering or punishment more than the location. It is also a name given to Satan as the king of the bottomless pit, or the abyssos (Revelation 9:10). The first phrase refers to the underworld, a place unseen to men, but not to God (Psalm 139:8). The point is that such a place we have so little conception of is entirely open before God. It follows then that human flesh is no covering to hide the hearts of men from God (Hebrews 4:12-13). The force of the proverb is to teach wisdom and the fear of the Lord.
