'Third Day' in the Bible

And be ready for the third day. For the third day Jehovah 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. Do not approach a woman.

And it happened on the third day in the morning, that there were thunders and lightnings, and a thick cloud upon the mountain. And the voice of the trumpet was exceedingly loud, so that all the people in the camp trembled.
