Verse 22 - Ye are witnesses against yourselves. Joshua has not disguised from them the difficulty of the task they have undertaken. Like a true guide and father, he has placed the case fully and fairly before them, and they have made their choice. He reminds them that their own words so deliberately uttered will be forever witnesses against them, should they afterwards refuse to keep an engagement into which they entered with their eyes open. They do not in any way shrink from the responsibility, and by accepting the situation as it is placed before them, render it impossible henceforth to plead ignorance or surprise as an excuse for their disobedience. And it is well to observe, as has been remarked above, that such an excuse never was pleaded afterwards, that the obligation, though evaded, was never disavowed.

24:15-28 It is essential that the service of God's people be performed with a willing mind. For LOVE is the only genuine principle whence all acceptable service of God can spring. The Father seeks only such to worship him, as worship him in spirit and in truth. The carnal mind of man is enmity against God, therefore, is not capable of such spiritual worship. Hence the necessity of being born again. But numbers rest in mere forms, as tasks imposed upon them. Joshua puts them to their choice; but not as if it were indifferent whether they served God or not. Choose you whom ye will serve, now the matter is laid plainly before you. He resolves to do this, whatever others did. Those that are bound for heaven, must be willing to swim against the stream. They must not do as the most do, but as the best do. And no one can behave himself as he ought in any station, who does not deeply consider his religious duties in family relations. The Israelites agree with Joshua, being influenced by the example of a man who had been so great a blessing to them; We also will serve the Lord. See how much good great men do, by their influence, if zealous in religion. Joshua brings them to express full purpose of heart to cleave to the Lord. They must come off from all confidence in their own sufficiency, else their purposes would be in vain. The service of God being made their deliberate choice, Joshua binds them to it by a solemn covenant. He set up a monument of it. In this affecting manner Joshua took his last leave of them; if they perished, their blood would be upon their own heads. Though the house of God, the Lord's table, and even the walls and trees before which we have uttered our solemn purposes of serving him, would bear witness against us if we deny him, yet we may trust in him, that he will put his fear into our hearts, that we shall not depart from him. God alone can give grace, yet he blesses our endeavours to engage men to his service.And Joshua said unto the people,.... In reply to their answer and resolution:

ye are witnesses against yourselves, that ye have chosen you the Lord God to serve him; that is, should they, after this choice of him, which they had so publicly declared, desert his service, and go into idolatry, their testimony would rise up against them, and they would, be self-condemned:

and they said, we are witnesses; should we ever apostatize from the Lord and his worship, we are content to have this our witness produced against us.
