'Third Day' in the Bible

and be ready for the third day, for on the third day the Lord will come down on Mount Sinai in the sight of all the people.

He said to the people, "Be ready for the third day. Do not go near your wives."

On the third day in the morning there was thunder and lightning and a dense cloud on the mountain, and the sound of a very loud horn; all the people who were in the camp trembled.
