'In that Day' in the Bible

Rejoice ye in that day, and leap for joy: for behold, your reward is great in heaven: for in the like manner did their fathers to the prophets.

But I say to you, that it shall be more tolerable in that day for Sodom than for that city.

In that day, he who shall be upon the house-top, and his furniture in the house, let him not come down to take it away: and he that is in the field, let him likewise not return back.
