The name Mamre in the Bible
Etymology of the name Mamre
The word mamre does not occur as such in Hebrew, but two distinct possible root-words catch the eye:
1) The noun ממר (memer) meaning bitterness, from the root מרר (marar) meaning to be bitter or being strong:
2) The root group מרא (mr'):
However, Jones' Dictionary of Old Testament Proper Names sees the name Mamre as a compilation. According to Jones, the double m comes from מן (min), meaning from, but from a variant of it: מם (mm), that none of the sources mention. The latter part of the name Mamre, according to Jones, comes from ראה (ra'ah), a verb meaning to see:
Hence Jones renders From Seeing, which seems a bit contrived.
NOBSE Study Bible Name List goes with the verb that means strong, and reads Firmness, probably because the name Mamre brings to mind the oaks of Mamre.
