The Hebrew meeh (plural meim) refers to the belly, bowels, intestines, womb, or inward parts of a person. It functions as both anatomical description and metaphor for the deepest seat of emotion and compassion. 'From the womb' (min-hameah) is an idiom for before birth or from one's core being.
Hebrew anthropology locates the deepest emotions in the meeh. When Joseph sees his brother Benjamin, his 'bowels yearned upon his brother' (Genesis 43:30 KJV) — intense compassion from the inward parts. Lamentations 1:20 cries, 'My bowels are troubled' at Jerusalem's desolation. Song of Solomon 5:4 describes the beloved's meeh being moved. In Isaiah 49:15, God's compassion is compared to a mother whose womb yearns for her child. The New Testament equivalent is splagchnon (G4698) — Jesus was 'moved with compassion' from His very gut. True mercy and compassion are visceral, not merely intellectual.
