Matthew 4:4
4. But he answered and said, It is written— (De 8:3).
Man shall not live by bread alone—more emphatically, as in the Greek, "Not by bread alone shall man live." but by every word that proceedeth out of the mouth of God—Of all passages in Old Testament Scripture, none could have been pitched upon more apposite, perhaps not one so apposite, to our Lord's purpose. "The Lord . . . led thee (said Moses to Israel, at the close of their journeyings) these forty years in the wilderness, to humble thee, and to prove thee, to know what was in thine heart, whether thou wouldest keep His commandments, or no. 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," &c., "Now, if Israel spent, not forty days, but forty years in a waste, howling wilderness, where there were no means of human subsistence, not starving, but divinely provided for, on purpose to prove to every age that human support depends not upon bread, but upon God's unfailing word of promise and pledge of all needful providential care, am I, distrusting this word of God, and despairing of relief, to take the law into My own hand? True, the Son of God is able enough to turn stones into bread: but what the Son of God is able to do is not the present question, but what is man's duty under want of the necessaries of life. And as Israel's condition in the wilderness did not justify their unbelieving murmurings and frequent desperation, so neither would Mine warrant the exercise of the power of the Son of God in snatching despairingly at unwarranted relief. As man, therefore, I will await divine supply, nothing doubting that at the fitting time it will arrive." The second temptation in this Gospel is in Luke's the third. That Matthew's order is the right one will appear, we think, quite clearly in the sequel. Matthew 4:7
7. Jesus said unto him, It is written again— (De 6:16), as if he should say, "True, it is so written, and on that promise I implicitly rely; but in using it there is another Scripture which must not be forgotten."
Thou shalt not tempt the Lord thy God—"Preservation in danger is divinely pledged: shall I then create danger, either to put the promised security skeptically to the proof, or wantonly to demand a display of it? That were 'to tempt the Lord my God,' which, being expressly forbidden, would forfeit the right to expect preservation." Matthew 4:10
10. Then saith Jesus unto him, Get thee hence, Satan—Since the tempter has now thrown off the mask, and stands forth in his true character, our Lord no longer deals with him as a pretended friend and pious counsellor, but calls him by his right name—His knowledge of which from the outset He had carefully concealed till now—and orders him off. This is the final and conclusive evidence, as we think, that Matthew's must be the right order of the temptations. For who can well conceive of the tempter's returning to the assault after this, in the pious character again, and hoping still to dislodge the consciousness of His Sonship, while our Lord must in that case be supposed to quote Scripture to one He had called the devil to his face—thus throwing His pearls before worse than swine?
for it is written— (De 6:13). Thus does our Lord part with Satan on the rock of Scripture. Thou shalt worship—In the Hebrew and the Septuagint it is, "Thou shalt fear"; but as the sense is the same, so "worship" is here used to show emphatically that what the tempter claimed was precisely what God had forbidden. the Lord thy God, and him only shalt thou serve—The word "serve" in the second clause, is one never used by the Septuagint of any but religious service; and in this sense exclusively is it used in the New Testament, as we find it here. Once more the word "only," in the second clause—not expressed in the Hebrew and the Septuagint—is here added to bring out emphatically the negative and prohibitory feature of the command. (See Ga 3:10 for a similar supplement of the word "all" in a quotation from De 27:26).
