'Third Day' in the Bible

and have been prepared for the third day; for on the third day doth Jehovah come down before the eyes of all the people, on mount Sinai.

and he saith unto the people, 'Be ye prepared for the third day, come not nigh unto a woman.'

And it cometh to pass, on the third day, while it is morning, that there are voices, and lightnings, and a heavy cloud, on the mount, and the sound of a trumpet very strong; and all the people who are in the camp do tremble.
