Only ye shall not eat the blood; ye shall pour it upon the earth as water.

Jamieson-Fausset-Brown Bible Commentary

De 12:16-25. Blood Prohibited.

16. ye shall not eat the blood; ye shall pour it upon the earth as water-The prohibition against eating or drinking blood as an unnatural custom accompanied the announcement of the divine grant of animal flesh for food (Ge 9:4), and the prohibition was repeatedly renewed by Moses with reference to the great objects of the law (Le 17:12), the prevention of idolatry, and the consecration of the sacrificial blood to God. In regard, however, to the blood of animals slain for food, it might be shed without ceremony and poured on the ground as a common thing like water-only for the sake of decency, as well as for preventing all risk of idolatry, it was to be covered over with earth (Le 17:13), in opposition to the practice of heathen sportsmen, who left it exposed as an offering to the god of the chase.

Matthew Henry's Concise Commentary

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.
