Suach appears in the genealogical records of the tribe of Asher, listed among the descendants in 1 Chronicles. Like many names in these tribal registers, it helps preserve family lineages and tribal identities during and after the exile. The meaning of the name is uncertain, though it may relate to roots involving sweeping or removal. Ancient versions render it variously, with the Septuagint offering 'Chouḥi' and other manuscripts suggesting 'Soue,' reflecting the challenges of preserving precise pronunciations across centuries.
