Verse 12. - And Jesus answering said unto him, It is said, Thou shalt not tempt the Lord thy God. It is remarkable that in these crowning instances of temptation, which no doubt were originally recounted by the Lord himself to the inner circle of the disciples, and from them passed into the regular course of instruction adopted by the Christian teachers of the first days, the Redeemer, in each of his three answers to the devil, uses words taken from two chapters (the sixth and eighth) of Deuteronomy. It has been suggested that the thoughts and expressions of this book were fresh in the mind of the tempted Christ, as he had probably, specially during his sojourn in the wilderness, used for his own study and meditation a book which told the story of Israel's wanderings in the desert for forty years. It seems, however, more likely that the Lord simply chose to frame his answers from a book with which every Israelite from his earliest yearn had been acquainted. The maxims and precepts of Deuteronomy were used in the education of every Hebrew child. Its devout and beautiful maxims were written on the phylacteries or frontiers which so many pious Jews were in the habit of wearing.

4:1-13 Christ's being led into the wilderness gave an advantage to the tempter; for there he was alone, none were with him by whose prayers and advice he might be helped in the hour of temptation. He who knew his own strength might give Satan advantage; but we may not, who know our own weakness. Being in all things made like unto his brethren, Jesus would, like the other children of God, live in dependence upon the Divine Providence and promise. The word of God is our sword, and faith in that word is our shield. God has many ways of providing for his people, and therefore is at all times to be depended upon in the way of duty. All Satan's promises are deceitful; and if he is permitted to have any influence in disposing of the kingdoms of the world and the glory of them, he uses them as baits to insnare men to destruction. We should reject at once and with abhorrence, every opportunity of sinful gain or advancement, as a price offered for our souls; we should seek riches, honours, and happiness in the worship and service of God only. Christ will not worship Satan; nor, when he has the kingdoms of the world delivered to him by his Father, will he suffer any remains of the worship of the devil to continue in them. Satan also tempted Jesus to be his own murderer, by unfitting confidence in his Father's protection, such as he had no warrant for. Let not any abuse of Scripture by Satan or by men abate our esteem, or cause us to abandon its use; but let us study it still, seek to know it, and seek our defence from it in all kinds of assaults. Let this word dwell richly in us, for it is our life. Our victorious Redeemer conquered, not for himself only, but for us also. The devil ended all the temptation. Christ let him try all his force, and defeated him. Satan saw it was to no purpose to attack Christ, who had nothing in him for his fiery darts to fasten upon. And if we resist the devil, he will flee from us. Yet he departed but till the season when he was again to be let loose upon Jesus, not as a tempter, to draw him to sin, and so to strike at his head, at which he now aimed and was wholly defeated in; but as a persecutor, to bring Christ to suffer, and so to bruise his heel, which it was told him, he should have to do, and would do, though it would be the breaking of his own head, Ge 3:15. Though Satan depart for a season, we shall never be out of his reach till removed from this present evil world.And Jesus answering said unto him, it is said,.... In Deuteronomy 6:16

Thou shalt not tempt the Lord thy God: in the text in Deuteronomy the words are, "ye shall not tempt the Lord your God." The second person plural, is here changed into the second person singular, to accommodate the words to Satan; whom Christ singly addresses, and makes answer to, and who was under this same general law as other rational creatures: and Jehovah may be called the Lord his God, as he is his creator and governor; by whom he is upheld in his being, and to whom he is subject, whether he will or not; though not his covenant God: and even if our Lord Jesus Christ is intended by the Lord God, as some think; he is God over all; over all principalities and powers, good and bad, by whom all are created, and in whom all consist; and whose power and authority over Satan and his angels, have abundantly appeared, in dispossessing devils out of men, sending them where he pleased, and in spoiling the powers of darkness, and in destroying him that had the power of death, the devil; and great insolence and wickedness it must be in a creature, to tempt the Lord his God, in any way, or form whatever; See Gill on Matthew 4:7
