Peter Pett's Commentary on the Bible
Leviticus 10 - Introduction
Chapter 10 A Stark Lesson and a Glorious Continuation.
But as so often when there is blessing, disobedience comes. Men have a strange ability to forget their own weakness and begin to think that they know better than God, to declare, ‘I am the captain of my soul, I am the master of my fate', even at such times as this. And thus it was with Aaron's elder sons. In overweening pride, or overweening folly, or both, they ignored what God had revealed and chose to follow their own way. They offered what Yahweh had not laid down in a way that demonstrated that they despised the set service of the tabernacle. They did not fully follow His will. Were they not now superior to common mortals? Had they not been with Yahweh in the Mount? (Exodus 24:9). Could they not now lead the way with their own innovations (which were simply pagan practises)?
This whole chapter concerns the holiness of God and the necessity for His people to be fully holy if they are to meet with Him. It first declares that His ordinances must be followed exactly. It then goes on to declare that the priests, in preparation for their service, are to keep away from alcohol when about to enter His presence, are to be careful to discern at all times between what is clean and unclean, and are therefore to avoid all that is ‘unclean', and that they are to ensure that the people are made fully aware of all covenant requirements, that they sin not in any way. It commences with this example of those who failed in holiness, and died for it, and then goes on to deal with various requirements in order to maintain the holiness of the Sanctuary, all of which are made more serious by these untimely deaths of those who failed to discern God's holiness. The stress all through is on the holiness of God.
