Joshua 22:7 - Joseph Benson’s Commentary on the Old and New Testaments

Then he blessed them Not only prayed for them as a friend, but blessed them as a father, in the name of the Lord, recommending them, their families, and affairs to the grace of God. It seems probable, from the manner in which this is stated, that this his blessing was peculiarly and separately given to the half-tribe of Manasseh. He was somewhat more nearly related to them than to the other two, as being an Ephraimite, and perhaps they might be more reluctant to depart than the others, as they were leaving one half of their own tribe behind them, and therefore might have more need than the others of the comfort and encouragement of his blessing.
