Kaah (כָּאָה) means to be downcast, dispirited, or crushed — a condition of broken morale or deep discouragement. The word appears in both Ezekiel (where it describes the heart broken by idolatry) and in poetic contexts of spiritual desolation.
The psychology of faith in the Hebrew Bible is remarkably honest about despair. Kaah names what happens when hope collapses — not as sin but as experience. Ezekiel 13:22 condemns false prophets who "dishearten (kaah) the righteous with lies" — causing God's people to lose their footing. This is a pastoral concern: false teaching that discourages genuine faith is uniquely destructive. The antidote in Scripture is not denial of pain but radical reliance: "Why are you downcast, O my soul? Put your hope in God" (Psalm 42:5).
Kaah is rare, appearing only twice in the OT. Its cluster with kaab (H3510, pain) and the broader lexicon of spiritual suffering shows that Hebrew had a nuanced vocabulary for inner states. The false prophet who "disheartens" (kaah) uses words as weapons against the soul — a form of spiritual violence. Jesus warned similarly against those who cause "little ones" to stumble.
