Deuteronomy 12:28

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.

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.'
