Tarry ye here for us - Probably Moses did not know that he was to continue so long on the mount, nor is it likely that the elders tarried the whole forty days where they were: they doubtless, after waiting some considerable time, returned to the camp; and their return is supposed to have been the grand cause why the Israelites made the golden calf, as they probably reported that Moses was lost.

Aaron and Hur are with you - Not knowing how long he might be detained on the mount, and knowing that many cases might occur which would require the interference of the chief magistrate, Moses constituted them regents of the people during the time he should be absent.

And he said unto the elders,.... The seventy elders which were selected out of the several tribes of Israel, and now about to return to the camp:

tarry ye here for us; meaning himself and Joshua, who was going with him:

until we come again unto you; perhaps Moses might not know how long his stay would be at the top of the mount, but supposed it would be some time by the provision he makes for hearing and adjusting cases in his absence:

and behold, Aaron and Hur are with you; Hur is not mentioned before, as being with Moses and the rest; but doubtless he was, at least it is highly probable he was one of the seventy elders of him; see Gill on Exodus 17:10.

if any man have any matters to do: any cases to be considered, any cause to be tried in difference between him and another man, and which cannot be determined by the inferior judges, is too difficult for them to take in hand:

let him come unto them; bring his case before them, and have their advice and opinion, and be determined by them.

And he said unto the elders, Tarry ye here for us, until we come again unto you: and, behold, Aaron and Hur are with you: if any man have any matters to do, let him come unto them.

14. he said unto the elders, Tarry ye here for us-There is a circular valley or hollow a good way up on the brow of Jebel Musa, which was their halting place, while he alone was privileged to ascend the highest peak. The people stood below, as in the "outer court," the elders in the "holy place," Moses, as a type of Christ, in "the holy of holies."

24:12-18 A cloud covered the mount six days; a token of God's special presence there. Moses was sure that he who called him up would protect him. Even those glorious attributes of God which are most terrible to the wicked, the saints with humble reverence rejoice in. And through faith in the atoning Sacrifice, we hope for greater honour than Moses ever enjoyed on earth. Now we see through a glass darkly, but when he shall appear, then face to face. This vision of God will continue with equal, if not increasing brightness of joy; not for a few days only, but through eternity.
