There failed not ought of any good thing,.... Not only every good thing in general, but every part and particular of that good thing; that, with all that was included in it, or were appendages to it, or circumstances of it:

which the Lord had spoken to the house of Israel; as of their deliverance out of Egypt, and passage through the Red sea and wilderness, with all conveniences for them therein; so of their passage through Jordan, success of their arms, the conquest of their enemies, possession of their land, a land flowing with milk and honey:

all came to pass; exactly, precisely, and punctually, even everything relative to their temporal and spiritual good: so all that God promises to his spiritual Israel, with respect to their present comfort or everlasting happiness, all is exactly fulfilled, all his promises in Christ are yea and amen.

Of all the good words which the Lord had spoken to the house of Israel not one had fallen, i.e., remained unfulfilled (Numbers 6:12); all had come to pass (vid., Joshua 23:14). הטּוב כּל־הדּבר relates to the gracious promises of God with regard to the peaceful possession of Canaan, which formed the basis of all the salvation promised to Israel, and the pledge of the fulfilment of all the further promises of God. Notwithstanding the fact that many a tract of country still remained in the hands of the Canaanites, the promise that the land of Canaan should be given to the house of Israel for a possession had been fulfilled; for God had not promised the immediate and total destruction of the Canaanites, but only their gradual extermination (Exodus 23:29-30; Deuteronomy 7:22). And even though the Israelites never came into undisputed possession of the whole of the promised land, to the full extent of the boundaries laid down in Numbers 34:1-12, never conquering Tyre and Sidon for example, the promises of God were no more broken on that account than they were through the circumstance, that after the death of Joshua and the elders his contemporaries, Israel was sometimes hard pressed by the Canaanites; since the complete fulfilment of this promise was inseparably connected with the fidelity of Israel to the Lord.

(Note: With reference to this apparent discrepancy between the promises of God and the actual results, Calvin observes, that "in order to remove every appearance of discrepancy, it is right to distinguish well between the clear, unwavering, and certain fidelity of God in the fulfilment of His promises, and the weakness and indolence of the people, which caused the blessings of God to slip from their hands. Whatever war the people undertook, in whatever direction they carried their standards, there was victory ready to their hand; nor was there anything to retard or prevent the extermination of all their enemies except their own slothfulness. Consequently, although they did not destroy them all, so as to empty the land for their own possession, the truth of God stood out as distinctly as if they had; for there would have been no difficulty in their accomplishment of all that remained to be done, if they had only been disposed to grasp the victories that were ready to their hand.")

There failed not ought of any good thing which the LORD had spoken unto the house of Israel; all came to pass.

21:45 All came to pass - Such an acknowledgment as this, here subscribed by Joshua, in the name of all Israel, we afterward find made by Solomon; and all Israel did in effect say amen to it, 1Kings 8:56. The inviolable truth of God's promise, and the performance of it to the uttermost, is what all believers in Christ have been always ready to bear their testimony to. And if in any thing it has seemed to come short, they have been as ready to take all the blame to themselves.

21:43-45 God promised to give to the seed of Abraham the land of Canaan for a possession, and now they possessed it, and dwelt therein. And the promise of the heavenly Canaan is as sure to all God's spiritual Israel; for it is the promise of Him that cannot lie. There stood not a man before them. The after-prevalence of the Canaanites was the effect of Israel's slothfulness, and the punishment of their sinful inclination to the idolatries and abominations of the heathen whom they harboured and indulged. There failed not aught of any good thing, which the Lord had spoken to the house of Israel. In due season all his promises will be accomplished; then will his people acknowledge that the Lord has exceeded their largest expectations, and made them more than conquerors, and brought them to their desired rest.
