John Gill's Bible Commentary Ver. 9. And that ye may prolong your days in the land , etc.] Not only enter it, and take possession of it, but continue in it long, which depended upon their obedience to the laws of God: which the Lord sware unto your fathers to give unto them and to their seed ; had promised with an oath, so that they might be assured of the enjoyment of it, though they could not be of their continuance in it, unless they obeyed the divine commands: a land that floweth with milk and honey ; abounds with all good things, whose fruits are fat as milk, and sweet as honey; so the Targum of Jonathan.
Matthew Henry Commentary
Verses 8-17 - Moses sets before them, for the future, life and death, the blessin and the curse, according as they did or did not keep God's commandment Sin tends to shorten the days of all men, and to shorten the days of people's prosperity. God will bless them with an abundance of all goo things, if they would love him and serve him. Godliness has the promis of the life that now is; but the favour of God shall put gladness int the heart, more than the increase of corn, and wine, and oil. Revol from God to idols would certainly be their ruin. Take heed that you hearts be not deceived. All who forsake God to set their affection upo any creature, will find themselves wretchedly deceived, to their ow destruction; and this will make it worse, that it was for want of taking heed.
