The community of Yahweh’s redeemed must practice disciplinary action against a member (one who lives “among you“) who has violated Yahweh’s command or continues to live in sin, specifically, idolatry (vv. 1-3, 6-8) to serve other gods. The key phrase is “among you” (vv. 1, 11, 13).
Various dietary laws concerning meat-eating are given in the first half of the chapter (vv. 1-21). The latter half emphasizes on tithing (vv. 22-29). God allows the tithing to provide for the Levites (priests and their family), aliens, orphans and widows. There is connection between tithing and blessings of Yahweh (v. 29).
Various ordinances given for the observance of the Sabbatical year, such as, grant remission of debts and releasing the salves. The reason is because Yahweh has been gracious to them (the people of Israel), they need to be gracious, which marks Yahweh’s covenant people from other nations.
Yahweh repeatedly exhorts his redeemed to remember what he has done for them (vv. 3 and 12). This exhortation is not anything new since he gave the same exhortations in the past. This does point out Yahweh’s reason. That is, because people often forget. Like the people of Israel, we get so caught up with ourselves and forget that apart from his redeeming grace, we all would not be where we are. In essence, all throughout our Christian life we are to remember and reflect on who he is, what he did, what he does, and what he will do. In fact, that is what the church must do and be committed to do. The church must prioritize and practice her commitment in re-presenting the gospel, God’s redeeming drama. Everything the church does and must do is precisely because of the gospel. The gospel shapes and must shape the entire church. So when the church gathers to worship, her songs must re-present the gospel, her prayers must re-present the gospel, her preaching must re-represent the gospel, and so on. And when she comes to the Lord’s Table she breaks bread and drink in remembrance of him, which by the way is the most visible and touchable re-presentation of the gospel.
