טֻחָה
(in the plural only) the kidneys (as being covered); hence (figuratively) the inmost thought
Definition
The Hebrew noun טֻחָה (ṭuchâh) appears only in the plural form (טֻחוֹת) and literally refers to the kidneys. In ancient Hebrew physiology, the kidneys were considered the seat of deep emotions, conscience, and moral discernment. This gives the word a strong figurative meaning, representing the innermost thoughts, feelings, and the hidden, most private part of a person. In Job 38:36, God asks who gave wisdom to the 'inward parts' (טֻחוֹת), poetically linking this organ to understanding. In Psalm 51:6, David prays that God desires truth in the 'inward being' (טֻחוֹת), emphasizing the moral and spiritual core where genuine repentance occurs.
Biblical Usage
This word is used only twice in the Old Testament, both times in poetic or wisdom literature. It is used figuratively to describe the deepest, most hidden part of a person's moral and intellectual being. In Job 38:36, it is paralleled with 'mind' (שֶׂכְוִי), highlighting its association with wisdom and understanding. In Psalm 51:6, a penitential psalm, it is the place where God desires truth, connecting it to conscience and authentic inner transformation.
Etymology
The noun טֻחָה (ṭuchâh) derives from the root טוח (ṭwḥ), meaning 'to overlay,' 'plaster over,' or 'cover.' This root is seen in verbs like טָחָה (H2909). The connection likely stems from the kidneys being perceived as 'covered' or protected within the body, or from the layer of fat that surrounds them. This physical sense of being covered or inner led naturally to the metaphorical meaning of hidden, inward thoughts.
Semantic Range
This word is theologically significant as it provides a Hebrew concept for the human conscience and the seat of moral and spiritual discernment. It teaches that God is concerned not with outward appearances but with the truth and integrity of a person's deepest self (Psalm 51:6). It enriches the understanding of biblical anthropology, showing that ancient Hebrews located wisdom, emotion, and moral consciousness in specific internal organs, emphasizing that true wisdom and repentance are matters of the heart—or in this case, the 'inward parts.'
In ancient Near Eastern culture, including Israel, internal organs like the heart, liver, and kidneys were not just seen as physical parts but as the centers of emotion, thought, and will. The kidneys (טֻחוֹת) were specifically associated with the most private thoughts, feelings, and moral reflections—the place of deepest self-examination. This differs from a modern, purely biological understanding of the kidneys' function.
לֵב (lēv, H3820) — the heart; a broader term for the inner person, including mind, will, and emotions. כִּלְיוֹת (kilyôṯ, H3629) — kidneys; the more common literal term for the organ, also used figuratively for the inward parts. נֶפֶשׁ (nepheš, H5315) — soul/life; refers to the whole person, one's life force or being.

How this works
Hebrew definitions are from Brown-Driver-Briggs (1906) and Strong's Exhaustive Concordance (1890), both public domain. BDB was groundbreaking for its era but reflects 19th-century assumptions about Semitic etymology. Modern scholarship (HALOT, DCH) has revised many entries. Use these definitions as a starting point for exploration, not as the final word on a term's meaning in context.
