Matthew 4:4 - Clarke's commentary and critical notes on the Bible

But he answered and said, It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God. But by (or, upon, επι) every word - Ρημα, in Greek, answers to דבר dabar in Hebrew, which means not only a word spoken, but also thing, purpose, appointment, etc. Our Lord's meaning seems to be this: God purposes the welfare of his creatures - all his appointments are calculated to promote this end. Some of them may appear to man to have a contrary tendency; but even fasting itself, when used in consequence of a Divine injunction, becomes a mean of supporting that life which it seems naturally calculated to impair or destroy.
