"From the wilderness and this Lebanon even to the great river, the river Euphrates" (1:4). Did Israel ever hold all of it?

The Euphrates is the border the LORD named to Abram, "from the river of Egypt to the great river, the river Euphrates" (Genesis 15:18), and Moses gave nearly the same borders as 1:4 (Deuteronomy 11:24). The Bible says several things, and they sit side by side. Moses had tied it to a condition: "For if you shall diligently keep all these commandments which I command you… then the LORD will drive out all these nations from before you" (Deuteronomy 11:22-23). Late in the book, "So the LORD gave to Israel all the land which he swore to give to their fathers. They possessed it, and lived in it" (21:43), and "Nothing failed of any good thing which the LORD had spoken" (21:45). Yet the LORD also tells the old Joshua, "there remains yet very much land to be possessed" (13:1), and after his death says, "I also will no longer drive out any of the nations that Joshua left when he died" (Judges 2:21). Later, "Solomon ruled over all the kingdoms from the River to the land of the Philistines, and to the border of Egypt" (1 Kings 4:21). This chapter doesn't say when all of it would be held; it gives the borders and the promise, "I have given you" (1:3).
