The Greek that is translated into English as “anchor (of the soul)” in English is, due to non-existing nautical language, rendered as xuk’chotontib (“that which becomes unmovable”) in Chol (source: Steven 1979, p. 75), as “iron crab” in Bawm Chin (source; David Clark), as “foundation” in Tsou (source: Peng Kuo-Wei), in Mossi as “a strong and steadfast picketting-peg” (source: Nida 1952, p. 46) and in Enxet as “that holds up like a rope” (source: See Jacob Loewen in The Bible Translator 1969, p. 24ff).
In Kouya the translation is “the foundation which keeps a house secure.” Eddie Arthur tells this story: “A slightly more prosaic example comes from Paul’s sea voyages in the Book of Acts. In Acts 27, when Paul’s ship was facing a huge storm, there are several references to throwing out the anchor to save the ship. Now the Kouya live in a tropical rain-forest and have no vessels larger than dug-out canoes used for fishing on rivers. The idea of an anchor was entirely foreign to them. However, it was relatively easy to devise a descriptive term along the lines of ‘boat stopping metal’ that captured the essential nature of the concept. This was fine when we were translating the word anchor in its literal sense. However, in Hebrews 6:19 we read that hope is an anchor for our souls. It would clearly make no sense to use ‘boat stopping metal’ at this point as the concept would simply not have any meaning. So in this verse we said that faith was like the foundation which keeps a house secure. One group working in the Sahel region of West Africa spoke of faith being like a tent peg which keeps a tent firm against the wind. I hope you can see the way in which these two translations capture the essence of the image in the Hebrews verse while being more appropriate to the culture.”
