The Greek that is translated in English as “brother” or “brother and sister” (in the sense of fellow believers), is translated with a specifically coined word in Kachin: “There are two terms for brother in Kachin. One is used to refer to a Christian brother. This term combines ‘older and younger brother.’ The other term is used specifically for addressing siblings. When one uses this term, one must specify if the older or younger person is involved. A parallel system exists for ‘sister’ as well. In [these verses], the term for ‘a Christian brother’ is used.” (Source: Gam Seng Shae)

In Matumbi is is translated as alongo aumini or “relative-believer.” (Source: Pioneer Bible Translators, project-specific notes in Paratext)

In Martu Wangka it is translated as “relative” (this is also the term that is used for “follower.”) (Source: Carl Gross)

In the German New Testament translation by Berger / Nord (publ. 1999) it is often translated as Mitchristen or “fellow Christians.”
