And Moses said unto them, stand still,.... Where they were; Aben Ezra says, at the door of the tabernacle of the congregation:

and I will hear what the Lord will command concerning you; as it was a singular case, of which there had been no instance before, Moses would not determine anything about it himself, but would inquire of the Lord his mind and will concerning it; and for that purpose, very probably, went into the most holy place, where the Lord had promised to meet him and commune with him, from off the mercy seat, about any matter of difficulty he should inquire about, Exodus 25:22.

Moses told them to wait (stand), and he would hear what the Lord, of whom he would inquire, would command.

And Moses said unto them, Stand still, and I will hear what the LORD will command concerning you.

8-14. Moses said unto them, Stand still, and I will hear what the Lord will command concerning you-A solution of the difficulty was soon obtained, it being enacted, by divine authority, that to those who might be disqualified by the occurrence of a death in their family circle or unable by distance to keep the passover on the anniversary day, a special license was granted of observing it by themselves on the same day and hour of the following month, under a due attendance to all the solemn formalities. (See on [67]2Ch 30:2). But the observance was imperative on all who did not labor under these impediments.

9:1-14 God gave particular orders for the keeping of this passover, and, for aught that appears, after this, they kept no passover till they came to Canaan, Jos 5:10. It early showed that the ceremonial institutions were not to continue always, as so soon after they were appointed, some were suffered to sleep for many years. But the ordinance of the Lord's Supper was not thus set aside in the first days of the Christian church, although those were days of greater difficulty and distress than Israel knew in the wilderness; nay, in the times of persecution, the Lord's Supper was celebrated more frequently than afterward. Israelites in the wilderness could not forget the deliverance out of Egypt. There was danger of this when they came to Canaan. Instructions were given concerning those who were ceremonially unclean, when they were to eat the passover. Those whose minds and consciences are defiled by sin, are unfit for communion with God, and cannot partake with comfort of the gospel passover, till they are cleansed by true repentance and faith. Observe with what trouble and concern these men complained that they were kept back from offering to the Lord. It should be a trouble to us, when by any occasion we are kept back from the solemnities of a sabbath or a sacrament. Observe the deliberation of Moses in resolving this case. Ministers must ask counsel of God's mouth, not determine according to their own fancy or affection, but according to the word of God to the best of their knowledge. And if, in difficult cases, time is taken to spread the matter before God by humble, believing prayer, the Holy Spirit assuredly will direct in the good and right way. God gave directions in this case, and in other similar cases, explanatory of the law of the passover. As those who, against their minds, are forced to absent themselves from God's ordinances, may expect the favours of God's grace under their affliction, so those who, of choice, absent themselves, may expect God's wrath for their sin. Be not deceived: God is not mocked.
