Joshua thought he had taken his last farewell of Israel in the solemn charge he gave them in the foregoing chapter, when he said, I go the way of all the earth; but God graciously continuing his life longer than expected, and renewing his strength, he was desirous to improve it for the good of Israel. He did not say, "I have taken my leave of them once, and let that serve;" but, having yet a longer space given him, he summons them together again, that he might try what more he could do to engage them for God. Note, We must never think our work for God done till our life is done; and, if he lengthen out our days beyond what we thought, we must conclude it is because he has some further service for us to do.
