Deuteronomy 12:28
Observe and hear all these words which I command thee, that it may go well with thee, and with thy children after thee for ever, when thou doest that which is good and right in the sight of the LORD thy God.
Observe and hear all these words which I command thee,.... Respecting the demolition of all monuments of idolatry, and bringing all holy things to the place the Lord should choose to dwell in; and eating common flesh in their own houses, only to be careful not to eat blood:
that it may go well with thee, and with thy children after thee for ever; for, as has been often observed, their continuance in the land of Canaan, and enjoyment of all good things in it, depended upon their obedience to the commands of God; see Isaiah 1:19
when thou doest that which is good and right in the sight of the LORD thy God; which is to do all his commandments; for these are what are good and right in his sight, and it is for the good of men to do them.
