Deuteronomy 12:28 Meaning and Commentary

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.

Deuteronomy 12:28 In-Context

26 "But you are to take the holy offerings you have and your vow offerings and go to the place the Lord chooses.
27 Present the meat and blood of your burnt offerings on the altar of the Lord your God. The blood of your [other] sacrifices is to be poured out beside the altar of the Lord your God, but you may eat the meat.
28 Be careful to obey all these things I command you, so that you and your children after you may prosper forever, because you will be doing what is good and right in the sight of the Lord your God.
29 "When the Lord your God annihilates the nations before you, which you are entering to take possession of, and you drive them out and live in their land,
30 be careful not to be ensnared by their ways after they have been destroyed before you. Do not inquire about their gods, asking, 'How did these nations worship their gods? I'll also do the same.'
