'In that Day' in the Bible

‘This is that which is consecrated to Aaron and that which is consecrated to his sons from the offerings by fire to the Lord, in that day when he presented them to serve as priests to the Lord.

For in that day he shall expiate for you, to cleanse you from all your sins: before Jehovah shall ye be clean.

In that day it shall be eaten; ye shall not leave from it till morning: I Jehovah.

Then the priest shall reckon unto him the worth of thy estimation, even unto the year of the jubile: and he shall give thine estimation in that day, as a holy thing unto the LORD.
