From Jesus, declaring to the Adversary:
ο δε αποκριθεις ειπεν γεγραπται ουκ επ αρτω μονω ζησεται
ανθρωπος αλλ επι παντι ρηματι εκπορευομενω δια στοματος θεου
(Mt. 4:4, as written in the characters of the plenarily inspired, inerrant, infallible, preserved Koine Greek language.) Which translated is (uninspired but accurate):
But He responded and stated, "It stands written.
'Man does not intrinically live upon a breadloaf only, but upon every utterance proceeding through God's mouth.' "
(A literal rendering into English, a nested quotation.)
And, of course. it is the prophet who says, "Thus sayeth The Lord" as Jesus as a prophet did to Satan, and Levi copied down the inspired words.
Jesus validated the authority of Holy Scripture found written in Deut. 8:3 by Moses: Deu 8:3 "And he humbled thee, and suffered thee to hunger, and fed thee with manna, which thou knewest not, neither did thy fathers know; that he might make thee know that man doth not live by bread only, but by every word that proceedeth out of the mouth of the LORD doth man live."
