Shichah (שִׁיחָה) means a pit or ditch, often used figuratively of a trap or snare. It appears about 7 times and is associated with the plots of the wicked that ensnare them in their own evil. Proverbs 22:14 uses it memorably: 'The mouth of an adulterous woman is a deep pit; a man who is under the LORD's wrath falls into it.'
The pit as metaphor for moral danger, divine judgment, and the trap of sin runs throughout the Old Testament. Shichah represents the consequence of wickedness 'digging a pit for others' and falling into it themselves — the lex talionis principle at work in wisdom literature. Psalm 7:15 and Proverbs 26:27 both state it plainly: 'Whoever digs a pit will fall into it.' This is not just karma but covenantal consequence — the moral order God has built into creation. Treachery is self-defeating. The cross reverses this: Christ fell into the pit of death so we would not.
