The Hebrew or Greek which are translated into English as “sackcloth” are rendered into Chamula Tzotzil as “sad-heart clothes.” (Source: Robert Bascom)
Pohnpeian and Chuukese translate it as “clothing-of sadness,” Eastern Highland Otomi uses “clothing that hurts,” Central Mazahua “that which is scratchy,” Tae’ and Zarma “rags” (Source: Reiling / Swellengrebel), and Tangale as “torn clothes that show contrition on the body” (source: Andy Warren-Rothlin). In the English translation by Goldingay (2018), “put on sackcloth” is translated as wrap on sack.
“In Turkana, a woman removes her normal everyday skin clothes and ornaments and wears rather poor skins during the time of mourning. The whole custom is known as ngiboro. It is very difficult to translate putting on sackcloth because even material like sacking is unfamiliar. The Haya, on the other hand, have a mourning cloth made out of the bark of a tree; and the use of this cloth is similar to the Jewish use of sackcloth. It was found that in both the Turkana and Ruhaya common language translations, their traditional mourning ceremonies were used.” (Source: Rachel Konyoro in The Bible Translator1985, p. 221ff. )

The Greek in James 1:25 that is translated as “the perfect law, the law of liberty” or similar in English is translated in Central Mazahua as “God has set us free so that we are able to obey his word,” in Rincón Zapotec as “the law of God which is perfect and is able to cause us to be saved,” in Mezquital Otomi as “God’s new word frees us in order that our life will be good,” and in Eastern Highland Otomi as “the new word which is like a law strengthens our hearts so that with pleasure we will obey it.”

The Greek that is translated as “elder” in most English versions (“presbyter” in The Orthodox New Testament, 2000) is translated as “Old-Man Leader” in Eastern Highland Otomi (source: John Beekman in Notes on Translation November 1964, p. 1-22) and in Bacama as mi kpan-kpani vɨnə hiutə: “big/old person of house of prayer” (source: David Frank in this blog post ).
