From: Burundi, East Africa
Source: Burundian (Kirundi) oral-tradition proverb (Umanika agatu wicaye mu kukamanura ugahaguruka); independently attributed to Burundi with this Kirundi original by zikoko.com ("13 African Proverbs and Their Meanings") and ikirundi.org's own Kirundi proverb collection (Imyibutsa y'Ikirundi) — not, as originally recorded here, Ewe (Agbemenu's Ewe collection could not be verified to contain it)
