Joshua 21: 43-45 (KJ) And the Lord gave unto Israel all the land which he sware to give unto their fathers; and they possessed it, and dwelt therein...And the Lord gave them rest round about, according to all that he sware unto their fathers; and there stood not a man of all their enemies before them; the Lord delivered all their enemies into their hand...There failed not aught of any good thing which the Lord had spoken unto the house of Israel; all came to pass.
22: 1-9 Reuben and Gad sent back to their homes.
When the Reubenites Gadites and half the tribe of Manasseh were settled on their lot they decided to build a Altar to the Lord but a misunderstanding by the Israelites prevailed but in the end it was all sorted out when they were told that it is a witness between us that the Lord is God.
And so God's people were finally in the promised land, a land of milk and honey. God also told them not to worry for the Lord their God will protect them.
