But take diligent heed, etc. - Let us examine the force of this excellent advice; they must ever consider that their prosperity and continued possession of the land depended on their fidelity and obedience to God; to this they must take diligent heed.
Do the commandment - They must pay the strictest regard to every moral precept.
And the law - They must observe all the rites and ceremonies of their holy religion.
Love the Lord your God - Without an affectionate filial attachment to their Maker, duty would be irksome, grievous, and impossible.
Walk in all his ways - They must not only believe and love, but obey: walk not in your own ways, but walk in those which God has pointed out.
Keep his commandments - They must love him with all their heart, soul, mind, and strength, and their neighbor as themselves.
Cleave unto him - They must be cemented to him, in a union that should never be dissolved.
Serve him - They must consider him as their Master, having an absolute right to appoint them when, where, how, and in what measure they should do his work.
With all your heart - Having all their affections and passions sanctified and united to him.
And with all your soul - Giving up their whole life to him, and employing their understanding, judgment, and will, in the contemplation and adoration of his perfections; that their love and obedience might increase in proportion to the cultivation and improvement of their understanding.

Now to the one half of the tribe of Manasseh Moses had given possession in Bashan,.... The kingdom of Og, see Deu 3:13,

but unto the other half thereof gave Joshua among their brethren on this side Jordan westward: of which an account is given, and the border of their lot described, Jos 17:1,

and when Joshua sent them also unto their tents, then he blessed them; it seems as if this half tribe was separately dismissed and blessed, they being more nearly related to Joshua, who was of the tribe of Ephraim, and so had a more particular dismission and blessing; and he took his leave of them in a different and affectionate manner. Kimchi makes mention of a Derash, or Exposition of theirs, which says, that after they had taken leave they stayed two days, and returned and took leave a second time, and which he understands of them all, and not of the half tribe only; but it is plainly the half tribe that is only spoken of.

get you unto your tents--that is, home; for their families had been left in fortified towns (Num 32:17).
