Exodus 19:11 Meaning and Commentary

Exodus 19:11

And be ready against the third day
Not the third day of the month, but the third day from hence, this being the fourth, and the morrow the fifth, and the third day, the day following that, the sixth, on which day it is generally agreed by the Jews that the law was given, (See Gill on Exodus 19:16)

for the third day the Lord will come down in the sight of all the
people upon Mount Sinai;
which must be understood, consistent with his omnipresence, and is only expressive of some visible display of his power, and of some sensible token of his presence to the people; he was now upon it in the pillar of cloud, but then he would appear in another manner, and descend in a thick cloud and fire, which all the people would see, though they could not see the similitude of anything in it.

Exodus 19:11 In-Context

9 Then the LORD said to Moses, “I will come to you in a thick cloud, Moses, so the people themselves can hear me when I speak with you. Then they will always trust you.” Moses told the LORD what the people had said.

10 Then the LORD told Moses, “Go down and prepare the people for my arrival. Consecrate them today and tomorrow, and have them wash their clothing.

11 Be sure they are ready on the third day, for on that day the LORD will come down on Mount Sinai as all the people watch.

12 Mark off a boundary all around the mountain. Warn the people, ‘Be careful! Do not go up on the mountain or even touch its boundaries. Anyone who touches the mountain will certainly be put to death.

13 No hand may touch the person or animal that crosses the boundary; instead, stone them or shoot them with arrows. They must be put to death.’ However, when the ram’s horn sounds a long blast, then the people may go up on the mountain. ”
