Joshua 23

​Joshua 23:1: 
​And it came to pass a long time after that the LORD had given rest unto Israel from all their enemies round about, that Joshua waxed old and stricken in age.

​Literally, was old, advanced in days (see Joshua 13:1). But this refers to a more advanced age still, when the patriarch felt his powers failing him, and desired, as far as his influence went, to preserve the Israelites in the path in which they had walked since their entrance into Canaan. Calvin has some good remarks on the "pious solicitude" shown by the aged warrior for those whom he had led in time of war and guided in time of peace. He seems to have sent for the chief men in Israel to his home at Timnath-Serah, where apparently he had led a retired and peaceful life, only coming forward to direct the affairs of the nation when necessity required. His address is simple and practical. He reminds them that they will soon lose the benefit of his experience and authority, and of the work that he had done, under God's direction, in settling them in the land. Then he proceeds to urge strict obedience to the law of God, reminding them that victory is assured to them, if they will but be true to themselves and their calling as the servants of God, but that as certainly as they neglect to do so, wrath and misery will be their portion. He emphasizes his words by reminding them how amply God had fulfilled his promise, and concludes with a picture of the evil which will befall them if they rebel against God. --Pulpit Commentary
