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.

The closing admonition is a further expansion of Deuteronomy 12:25 (see at Deuteronomy 11:21). - In Deuteronomy 12:29-31, the exhortation goes back to the beginning again, viz., to a warning against the Canaanitish idolatry (cf. Deuteronomy 12:2.). When the Lord had cut off the nations of Canaan from before the Israelites, they were to take heed that they did not get into the snare behind them, i.e., into the sin of idolatry, which had plunged the Canaanites into destruction (cf. Deuteronomy 7:16, Deuteronomy 7:25). The clause "after they be destroyed from before thee" is not mere tautology, but serves to depict the danger of the snare most vividly before their eyes. The second clause, "that thou inquire not after them" (their gods), etc., explains more fully to the Israelites the danger which threatened them. This danger was so far a pressing one, that the whole of the heathen world was animated with the conviction, that to neglect the gods of a land would be sure to bring misfortune (cf. 2 Kings 17:26).

Observe and hear all these words which I command thee, that it may go {o} 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.

(o) God by promise binds himself to do good to those who obey his word.

12:5-32 The command to bring ALL the sacrifices to the door of the tabernacle, was now explained with reference to the promised land. As to moral service, then, as now, men might pray and worship every where, as they did in their synagogues. The place which God would choose, is said to be the place where he would put his name. It was to be his habitation, where, as King of Israel, he would be found by all who reverently sought him. Now, under the gospel, we have no temple or altar that sanctifies the gift but Christ only: and as to the places of worship, the prophets foretold that in every place the spiritual incense should be offered, Mal 1:11. Our Saviour declared, that those are accepted as true worshippers, who worship God in sincerity and truth, without regard either to this mountain or Jerusalem, Joh 4:21. And a devout Israelite might honour God, keep up communion with him, and obtain mercy from him, though he had no opportunity of bringing a sacrifice to his altar. Work for God should be done with holy joy and cheerfulness. Even children and servants must rejoice before God; the services of religion are to be a pleasure, and not a task or drudgery. It is the duty of people to be kind to their ministers, who teach them well, and set them good examples. As long as we live, we need their assistance, till we come to that world where ordinances will not be needed. Whether we eat or drink, or whatever we do, we are commanded to do all to the glory of God. And we must do all in the name of the Lord Jesus Christ, giving thanks to the Father through him. They must not even inquire into the modes and forms of idolatrous worship. What good would it do them to know those depths of Satan? And our inward satisfaction will be more and more, as we abound in love and good works, which spring from faith and the in-dwelling Spirit of Christ.
