“It is written, Man does not live by bread alone, but by every word that proceeds out of the mouth of God.” Quoted from Deuteronomy. 8:3. Jesus’ quotation of Deuteronomy was not exact, but was very close. He never claimed to make an exact quotation. It is noteworthy that Deuteronomy 8:3 is about people living by what God said in the wilderness when they were hungry and wanted a variety of food, and here Jesus quotes the verse when he is in the desert and hungry.
