John Gill Commentary Joshua 21:45

"There failed not aught of any good thing which Jehovah had spoken unto the house of Israel; all came to pass." — Joshua 21:45 (ASV)

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 his promises in Christ are yea and amen.
