Peter Pett's Commentary on the Bible
Deuteronomy 12:26-28
But All Holy Things (Things Dedicated to Yahweh) Must Be Taken To The Sanctuary (Deuteronomy 12:26).
But this does not apply to ‘your holy things'. In mind here are all the things which Yahweh has required from them. Specific appointed offerings, sacrifices offered in accordance with requirements, tithes, firstlings and so on. These may only be offered at the sanctuary.
‘ Only your holy things which you have, and your vows, you shall take, and go to the place which Yahweh shall choose,'
The holy things are those which God has appointed to be set apart for Himself. They also include votive offerings, which by their very nature have become separated to God. These they must take and go with them to the place which Yahweh chooses, the sacred place where He is pleased to dwell, and which He has appointed (except when He directs otherwise). Everything is under His direction.
‘ And you shall offer your whole burnt offerings, the flesh and the blood, on the altar of Yahweh your God, and the blood of your sacrifices shall be poured out on the altar of Yahweh your God, and you shall eat the flesh.'
Here whole burnt offerings are distinguished from sacrifices. The whole of the whole burnt offerings must be offered on the altar, in one way or another, both flesh and blood. But of the sacrifices the blood must be poured on the altar, but the flesh could be eaten, some only by the priest, other by both the priest and the offerer, depending on the nature of the sacrifices, and in accordance with the requirements laid down. This was a summarised generalisation. There were also some sacrifices which had to be completely burnt. See for all this Leviticus 1-7.
Once again we are reminded that there are certain things that must come first in our lives. There are too many Christians who are happy to seek full physical satisfaction, because ‘their souls desire to eat flesh', but come short in wholehearted dedication and commitment to God of their time, their money and their lives. If we do not honour God in the holy things, that is, in our spiritual lives, or if we do not offer Him the whole burnt offering of ourselves, we need to question whether we are really His at all.
‘ Observe and hear all these words which I command you, that it may go well with you, and with your children after you for ever, when you do what is good and right in the eyes of Yahweh your God.'
Compare Deuteronomy 12:25. Moses again reiterates that they must observe and hear all the words that He commands them, as their future blessing and wellbeing, and that of their children, will depend on it. In one way or another this is constantly repeated (for ‘observe' and ‘hear' see Deuteronomy 6:3; Deuteronomy 15:5; Deuteronomy 18:14; but the general idea is multiplied e.g. Deuteronomy 4:1; Deuteronomy 5:1; and often). They must be in no doubt about the fact that all the blessings that they will receive are gifts from Yahweh, and are therefore dependent on obedience to the covenant in all its aspects (which included making themselves aware of what was required, which is where the Levites could help).
