Deuteronomy 12:28

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.
