1 Kings 19:8

And he arose, and did eat and drink, and went in the strength of that meat forty days and forty nights [Cf. Exodus 24:18 ; Exodus 34:28 ; Deuteronomy 9:9 , Deuteronomy 9:25 ; Jonah 3:4 ; Matthew 4:2 ; Acts 1:3 . But the primary reference is perhaps to the "forty days and forty nights" which Moses spent in Horeb, during which he "neither did eat bread nor drink water" ( Deuteronomy 9:9 ), or to the forty years during which Israel was sustained in this same desert with "angels' food" ( Psalms 78:25 ). It is noteworthy how both Moses and Elias were precursors of our Lord in a forty days' fast. "The three great rasters met gloriously on Tabor" (Hall). It is not implied that it took the prophet the whole of this time to reach Horeb, which is only distant from Beer-sheba some 130 miles. "There are eleven days' journey from Horeb, by the way of Mount Seir to Kadesh Barnes" ( Deuteronomy 1:2 ). It is of course possible that he wandered aimlessly hither and thither during this period, but it seems better to understand the words of the whole of his desert sojourn] unto Horeb the mount of God. [See note on 1 Kings 8:9 . It is just possible that Horeb was already known as "the mount of God" at the time God appeared to Moses there—the whole of the Sinaitic peninsula was sacred in the eyes of the Egyptians; but it is more probable that this designation is used in Exodus 3:1 prophetically, and that it was Bestowed on the Mount of the Law because of the special revelation of the Godhead there ( Exodus 3:6 ; Exodus 19:3 , Exodus 19:11 , Exodus 19:18 ; Deuteronomy 1:6 ; Deuteronomy 4:10 ; Deuteronomy 5:2 , etc.)]
