'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 told the people, "Be ready for the third day; don't go near a woman."

When morning came on the third day, there was thunder and lightning, with a heavy cloud over the mountain, and the very loud sound of a ram's horn. All the people in the camp trembled.
