Moses Reminds Them That Yahweh Will Cast Them From The Land If They Hesitate To Enter It, As He Did Before (Numbers 32:10-15).
“ And Yahweh's anger was kindled in that day, and he swore, saying,”
And the result was that Yahweh's anger was kindled against them, so that He swore what He would do to them.
“ Surely none of the men that came up out of Egypt, from twenty years old and upward, shall see the land which I swore to Abraham, to Isaac, and to Jacob; because they have not wholly followed me, except Caleb the son of Jephunneh the Kenizzite, and Joshua the son of Nun; because they have wholly followed Yahweh.”
For He had declared that none of them would be allowed to see the land that they had rejected, the land that He had sworn to give to their forefathers. None of the males from twenty years old and upwards would be allowed to enter it, apart from Caleb and Joshua. They would be the exceptions because they had wholly followed Yahweh.
“ And Yahweh's anger was kindled against Israel, and he made them wander to and fro in the wilderness forty years, until all the generation, that had done evil in the sight of Yahweh, was consumed.”
Thus was Yahweh's anger kindled against them, and He made them wander to and fro in the wilderness for forty years until the whole of that generation was consumed, because they had done evil in His sight.
“ And, behold, you are risen up in your fathers' stead, an increase of sinful men, to augment yet the fierce anger of Yahweh towards Israel.”
And now here they were doing exactly the same thing. They were rising up in their father's place, adding to those who had been sinful men by being equally sinful, stoking up the fierce anger of Yahweh against Israel.
“ For if you turn away from after him, he will yet again leave them in the wilderness, and you will destroy all this people.”
For did they not realise what the result would be? If they turned away from following Yahweh, and refused to enter the land which God had promised their forefathers to give them? He would again leave them in the wilderness, along with all their fellow-tribesmen, and all of them would be destroyed, and it would all be the fault of the Reubenites and the Gadites.
