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 thou shalt take thy holy things, if thou hast any, and thy vowed-offerings, and come to the place which the Lord thy God shall choose to have his name named upon it.
27 And thou shalt sacrifice thy whole-burnt-offerings, thou shalt offer the flesh upon the altar of the Lord thy God; but the blood of thy sacrifices thou shalt pour out at the foot of the altar of the Lord thy God, but the flesh thou shalt eat.
28 Beware and hearken, and thou shalt do all the commands which I charge thee, that it may be well with thee and with thy sons for ever, if thou shalt do that which is pleasing and good before the Lord thy God.
29 And if the Lord thy God shall utterly destroy the nations, to whom thou goest in thither to inherit their land, from before thee, and thou shalt inherit it, and dwell in their land;
30 take heed to thyself that thou seek not to follow them after they are destroyed before thee, saying, How do these nations act towards their gods? I will do likewise.
