Matthew 4:4

Ὁ δὲ ἀποκριθεὶς εἶπεν Γέγραπται Οὐκ ἐπ’ ἄρτῳ μόνῳ ζήσεται ὁ ἄνθρωπος Ἀλλ’ ἐπὶ παντὶ ῥήματι ἐκπορευομένῳ διὰ στόματος Θεοῦ

ho de apokritheis eipen Gegraptai Ouk ep’ artō monō zēsetai ho anthrōpos all’ epi panti rhēmati ekporeuomenō dia stomatos Theou

- however He answering said It has been written: Not in bread alone shall live - a man but at every word coming out on account of [the] mouth of God
