16 The glory of Yahweh settled on Mount Sinai, and the cloud covered it six days. The seventh day he called to Moses out of the midst of the cloud.

And the seventh day he called - It is very likely that Moses went up into the mount on the first day of the week; and having with Joshua remained in the region of the cloud during six days, on the seventh, which was the Sabbath, God spake to him, and delivered successively to him, during forty days and forty nights, the different statutes and ordinances which are afterwards mentioned.
And the glory of the Lord abode upon Mount Sinai,.... The divine Shechinah or Majesty, some visible token of it, an exceeding great brightness and splendour:
and the cloud covered it six days; either the glory of the Lord, so that it could not be seen it had been; or the mount, as Jarchi; but that is observed before, unless repeated for the sake of the time it covered it, six days; or him, Moses, as some in Jarchi, who for six days together was covered with a thick cloud, so that he was not seen by any while on the mountain; and thus he remained, until he was admitted into the immediate presence of God, for which he was now preparing: what he did, or was made known to him during this time, is not said; it is probable his thoughts were employed about the glory and greatness of the divine Being; and as he was abstracted from earthly men and things, he was more at leisure to contemplate on divine and heavenly things, and so was more fitted for an intercourse with God, and had more courage and presence of mind to enter into it:
and on the seventh day he called unto Moses out of the midst of the cloud; in which the glory of God was, and which seems to favour the first sense of the preceding clause, that it was the glory of God the cloud covered.
A cloud covered the mount six days - A visible token of God's special presence there, for he so shews himself to us, as at the same time to conceal himself from us, he lets us know so much as to assure us of his power and grace, but intimates to us that we cannot find him out to perfection. During these six days Moses staid waiting upon the mountain, for a call into the presence - chamber. And on the seventh day - Probably the sabbath - day, he called unto Moses. Now the thick cloud opened in the sight of all Israel, and the glory of the Lord broke forth like devouring fire.
