Bawm build with bamboo and thatch in their mountainous forests. They made the apostles and prophets become the roof ridge pole and Jesus the central uprights which support it. I asked why not the corner uprights since Greek has a term that is translated in English as ‘cornerstone.’ Bawm translators responded that the central uprights are more important than the corner ones, and Greek refers to the most important stone. (“Corner uprights” used in 1Tim 3:15.) (Source: David Clark)
In Mono, translators used “main post,” in Martu Wangka “two forked sticks with another long strong stick laid across” (see also 1 Peter 2:6-7.), and in Arrernte, the translation in 1Pet 2:7 (in English translation: “the stone . . . became the very cornerstone”) was rendered as “the foundation… continues to be the right foundation.” (Source for this and two above: Carl Gross)
Likewise, in Uripiv it also is the “post” (source: Ross McKerras) as well as in Sabaot (source Jim Leonhard in Holzhausen / Riderer 2010, p. 50)
In Ixcatlán Mazatec it is translated with a term denoting the “the principal part of the ‘house’ (or work)” (Source: Robert Bascom), in Enlhet as “like the house-root” (source: Jacob Loewen in The Bible Translator 1969, p. 24ff.), in Q’anjob’al it is translated with with the existing idiom “ear of the house.” (Source: Newberry and Kittie Cox in The Bible Translator 1950, p. 91ff.), in Desano as “main support of the house,” and in Tataltepec Chatino as “the best stone” (source for this and one above: Viola Waterhouse in Notes on Translation August 1966, p. 86ff.).
Shuar translates as “that stone was placed to the main house pole.” The Shuar use stones in house building either at the bottom of the posthole as a base for the house pole to rest on, or as chocking material around the post to hold it firm. Either function is acceptable here particularly as applied to the main house-pole. In Ocotlán Zapotec it is “master stone of the house.” This is a special stone they put into the foundation as sort of a guide stone of how the foundation is to true up. (Source: B. Moore / G. Turner in Notes on Translation 1967, p. 1ff.)
