The Greek and Ge’ez that is typically translated as «gentleness» in English is translated in various ways:

• Suki: gitusaena inae or «not-snatching way» (source L. and E. Twyman in The Bible Translator 1953, p. 91ff. )
• Tibetan: sems dul ba (སེམས་​དུལ་​བ།), lit. «mind + tame» (source: gSungrab website )
• Ojitlán Chinantec: «make hearts good»
• Isthmus Mixe: «speak with patience»
• Tenango Otomi: «speak in a good way»
• Tabasco Chontal: «mind should be good with all» (source for this and three above: John Beekman & Harwood Hess in Notes on Translation, March 1963, p. 1ff.)
