Verses 1-49 This is a brief review of the travels of the children of Israel through the wilderness. It is a memorable history. In their travels towards Canaan they were continually on the remove. Such is our state in this world; we have here no continuing city, and all our removes in this world are but from one part a desert to another. They were led to and fro, forward and backward, yet were all the while under the direction of the pillar of cloud and fire. God led them about, yet led them the right way. The way God takes in bringing his people to himself is always the best way, though it does not always seem to us the nearest way. Former events are mentioned. Thus we ought to keep in mind the providences of God concerning us and families, us and our land, and the many instances of that Divine care which has led us, and fed us, and kept us all our days hitherto. Few periods of our lives can be thought upon, without reminding us of the Lord's goodness, and our own ingratitude and disobedience: his kindness leaves us without excuse for our sins. We could not wish to travel over again the stages we have passed, unless we could hope, by the grace of God, to shun the sins we then committed, and to embrace such opportunities of doing good as we have let slip. Soon will our wanderings end, and our eternal state be fixed beyond recall; how important then is the present moment! Happy are those whom the Lord now guides with his counsel, and will at length receive to his glory. To this happiness the gospel calls us. Behold now is the accepted time, now is the day of salvation. Let sinners seize the opportunity, and flee for refuge to the hope set before them. Let us redeem our time, to glorify God and serve our generation; and he will carry us safely through all, to his eternal kingdom.
Verses 50-56 Now that they were to pass over Jordan, they were entering again into temptation to follow idols; and they are threatened that, if they spared either the idols or the idolaters, their sin would certainly be their punishment. They would foster vipers in their own bosoms. The remnant of the Canaanites, if they made any peace with them, though but for a time, would be pricks in their eyes, and thorns in their sides. We must expect trouble and affliction from whatever sin we indulge; that which we are willing should tempt us, will vex us. It was intended that the Canaanites should be put out of the land; but if the Israelites learned their wicked ways, they also would be put out. Let us hear this and fear. If we do not drive out sin, sin will drive us out. If we are not the death of our lusts, our lusts will be the death of our souls.
