Unchangeable (276) (ametathetos from a = without + metatíthemi = change condition or place, transfer, put in another place) literally never changing, not to be transferred. The idea is that which is fixed, unalterable or immutable. This word was used in secular Greek in the context of wills and contracts and signified a stipulation that could not be disregarded or annulled. Once properly made a will was ametathetos unchangeable by anyone but the maker. The writer of Hebrews uses this word (in the only 2 uses in Scripture in Hebrews 6:17 [note] and Hebrews 6:18 [note]) with powerful, well known forensic (legal) ramifications (immutability of a legally written will) to add to the force of the encouragement he extended to his readers.
