Deuteronomy 3:27

He is ordered to take a full view of the countries allotted by God to the Hebrews; and if we consider that the territory, as far as the Euphrates, was promised to them, if they would continue to be faithful, and that it was made tributary, under Solomon, we need not wonder if Moses should be pleased to behold it, chap. i. 7.
