Matthew 4:2

“And when he had fasted forty days. etc.] As Moses did, when he was about to deliver the law to the Israelites, (<023428>Exodus 34:28) and as Elijah did, when he bore his testimony for the Lord of hosts, (<111908>1 Kings 19:8) so did Christ, when he was about to publish the Gospel of his grace, and bear witness to the truth. “Forty nights” as well as days, are mentioned; partly to show that these were whole entire days, consisting of twenty four hours; and partly to distinguish this fast of Christ from the common fastings of the Jews, who used to eat in the night, though they fasted in the day: for according to their canons f193, they might eat and drink as soon as it was dark, and that till…”

“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…”

“Had fasted - Abstained from food. Forty days and forty nights - It has been questioned by some whether Christ abstained wholly from food, or only from the food to which he was accustomed. Luke says Luke 4:2 that he ate nothing. This settles the question. Mark says Mark 1:13 that angels came and ministered unto him. At first view this would seem to imply that he did eat during that time. But Mark does not mention the time when the angels performed this office of kindness, and we are at liberty to suppose that he means to say that it was done at the close of the 40 days; and the rather as Matthew, after giving an account of the temptation, says the same thing Matthew 4:2. There are other…”

“Having fasted - Whereby doubtless he received more abundant spiritual strength from God. Forty days and forty nights - As did Moses, the giver of the law, and Elijah, the great restorer of it. He was afterward hungry - And so prepared for the first temptation. Matthew 4:3”

“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).”

“fasted: Exo 24:18, Exo 34:28; Deu 9:9, Deu 9:18, Deu 9:25, Deu 18:18; Kg1 19:8; Luk 4:2 he was: Mat 21:18; Mar 11:12; Joh 4:6; Heb 2:14-17 Matthew 4:3”
