A word rooted in physical well-being that carries a powerful metaphorical extension. In the Gospels it describes people made whole after miraculous healing -- the man at the pool of Bethesda whom Jesus asks 'Do you want to be made well?' (John 5:6), and the woman healed of her bleeding (Mark 5:34). The Spanish 'sana' and German 'gesund' capture this bodily wholeness. In the Pastoral Epistles, Paul repurposes the same word for doctrine that is spiritually robust and uncorrupted, 'sound teaching' (Titus 2:1), bridging body and belief in a single adjective.
