Verse 31. - For even their sons and their daughters have they burnt in the fire to their gods. Elsewhere the phrase used is "make to pass through the fire "(Deuteronomy 18:10), or simply "make to pass through to Molech" (Leviticus 18:21; Jeremiah 32:35). This has led some to maintain that the ceremony described was merely a februation, a lustration by fire, and not an actual burning alive of these victims; but there can be no doubt that both among the Ammonites and the Phoenicians, and indeed wherever the worship of Baal or Molech was followed, the offering of children in sacrifice by burning prevailed (Munter, 'Religion der Karthager,' p. 18, 2nd edit.; Selden, 'De Diis Syris Syntag,' i.e. 6, pp. 93, 257, edit. Beyer, Amst., 1680).

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.Thou shalt not do so unto the Lord thy God,.... Not serve and worship him after the manner of the Gentiles, nor introduce their rites and customs into his service, used by them in the worship of their gods:

for every abomination which he hateth have they done unto their gods; as murder, adultery, &c. which God has expressed his aversion to, and indignation at; one instance of the former sort is given here:

for even their sons and their daughters they have burnt in the fire to their gods; not only men have they sacrificed to them, but such near relations; and not only caused them to pass through the fire, but burnt them in it; so the Carthaginians are said to do, who learned this inhuman practice from the Phoenicians; they were a colony of the inhabitants of this land of Canaan. Of the Phoenicians Porphyry says (i), that in great calamities, as war or pestilence, they sacrificed to Saturn some one of those that were dearest to them, appointed by suffrage. The Phoenician history, adds he, is full of such sacrifices, which Sanchoniatho wrote in the Phoenician language; and Curtius says (k), this custom of sacrificing a fine boy to Saturn was received by the Carthaginians from their founders (the Tyrians and Phoenicians), and which they continued even to the destruction of their city.
