Jesus quoted from memory.............
Hmmm. If so, was Jerome correct in his translation of His quoted memory? :)
Although He, as Jehovah, did cause Moses to write down His Words, it was to that written Word that He referred to in reproving Satan, thus authorizing its standing alone as irrefutable and eternal. Mt. 4:4 in Gk, "It is written" is in the perfect tense, not "It was written." Most certainly Jesus did quote from memory, of what He had caused to be written. He also referred to the Word as the "hrema" the spoken word, as having come out of the mouth of God (that is, of His Own mouth), IIRC.
