'Third Day' in the Bible

and be ready for the third day, for the third day LORD will come down in the sight of all the people upon mount Sinai.

And he said to the people, Be ready for the third day. Come not near a woman.

And it came to pass on the third day, when it was morning, that there were thunders and lightnings, and a thick cloud upon the mount, and the voice of an exceedingly loud trumpet. And all the people who were in the camp trembled.
