Matthew 4:2

And when he had fasted forty days and forty nights--Luke says "When they were quite ended" (Luk 4:2). he was afterward an hungered--evidently implying that the sensation of hunger was unfelt during all the forty days; coming on only at their close. So it was apparently with Moses (Exo 34:28) and Elijah (Kg1 19:8) for the same period. A supernatural power of endurance was of course imparted to the body, but this probably operated through a natural law--the absorption of the Redeemer's Spirit in the dread conflict with the tempter. (See on Act 9:9). Had we only this Gospel, we should suppose the temptation did not begin till after this. But it is clear, from Mark's statement, that "He was in the wilderness forty days tempted of Satan" (Mar 1:13), and Luke's, "being forty days tempted of the devil" (Luk 4:2), that there was a forty days' temptation before the three specific temptations afterwards recorded. And this is what we have called the First Stage. What the precise nature and object of the forty days' temptation were is not recorded. But two things seem plain enough. First, the tempter had utterly failed of his object, else it had not been renewed; and the terms in which he opens his second attack imply as much. But further, the tempter's whole object during the forty days evidently was to get Him to distrust the heavenly testimony borne to Him at His baptism as THE SON OF GOD--to persuade Him to regard it as but a splendid illusion--and, generally, to dislodge from His breast the consciousness of His Sonship. With what plausibility the events of His previous history from the beginning would be urged upon Him in support of this temptation it is easy to imagine. And it makes much in support of this view of the forty days' temptation that the particulars of it are not…

John Baptist said concerning Christ, He must increase, but I must decrease; and so it proved. For, after John had baptized Christ, and borne his testimony to him, we hear little more of his ministry; he had done what he came to do, and thenceforward there is as much talk of Jesus as ever there had been of John. As the rising Sun advances, the morning star disappears. Concerning Jesus Christ we have in this chapter, I. The temptation he underwent, the triple assault the tempter made upon him, and the repulse he gave to each assault (Mat 4:1-11). II. The teaching work he undertook, the places he preached in (Mat 4:12-16), and the subject he preached on (Mat 4:17). III. His calling of disciples, Peter and Andrew, James and John (Mat 4:18-22). IV. His curing diseases (Mat 4:23, Mat 4:24), and the great resort of the people to him, both to be taught and to be healed.

4:2 forty days and forty nights (see Exod 24:18; 34:28; 1 Kgs 19:8): Israel was tested in the wilderness for forty years (Exod 16:35; Deut 1:3).
