Matthew Poole and continuators on Exodus 24:16

16 And the glory of the LORD abode upon mount Sinai, and the cloud covered it six dayes: and the seventh day he called unto Moses out of the midst of the cloud.

(i. e.) The tokens of his glorious presence in the fire, ver. 17. Deut. 4. 36.

From the eyes of the people.

So long God made Moses wait, either to exercise his humility, devotion, and dependance upon God: Or to prepare him by degrees for so great a work: Or because this was the Sabbath day, called therefore the seventh with an emphatical article: And God might chuse that day, for the beginning of that glorious work to put the greater honour upon it and oblige the people to a stricter observance of it. So it was upon a Lords Day that St. Iohn had his Revelation delivered to him, Rev. 1. 10.
