(30) Take heed to thyself that thou be not snared.--A necessary caution. "The fear" of heathen deities often attached itself to their seats of worship. It was found necessary to caution Israel against the fear of them and the dread of them in much later times. (See Jeremiah 10:2-5.)

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.Take heed to thyself, that thou be not snared by following them,.... Their examples and customs, and so be drawn into the same idolatrous practices; see Psalm 106:35, after that they be destroyed from before thee; for their idolatries and other sins:

and that thou inquire not after their gods; what they were, their names, forms, and figures:

saying, how did these nations serve their gods? what was the manner of worship they gave them? what rites, customs, and ceremonies did they use in their adoration of them?

even so will I do likewise; or however, if this was not determined on when the inquiries were made, there was danger that this would be the result of them, and therefore the caution is given.
