🔼The name Shaveh in the Bible
It's not wholly clear whether Shaveh is a Biblical name or not, although from ancient times the various translations in general seem to think so. Among the exceptions is the Lutheran translation of 1545, which uses the German "Felt" (= field).
The name or word Shaveh occurs in Genesis 14:17, where Abraham meets Melchizedek in either a field or else a place named Shaveh. The text reads: "in the valley [of] shaveh, which is the valley (same word) [of] the king".
Translations tend to choose to see Shaveh as a name also because it would correspond with the name Shaveh-kiriathaim, which occurs in Genesis 14:5, and which Luther translates with "[in dem] Felde Kiriathaim".
