'Fifth' in the Bible

speaking unto the priests who are at the house of Jehovah of Hosts, and unto the prophets, saying, 'Do I weep in the fifth month -- being separated -- as I have done these so many years?'

When ye fasted with mourning in the fifth and in the seventh months -- even these seventy years -- did ye keep the fast to Me -- Me? And when ye eat, and when ye drink, is it not ye who are eating, and ye who are drinking?

Thus said Jehovah of Hosts: The fast of the fourth, and the fast of the fifth, and the fast of the seventh, and the fast of the tenth months, are to the house of Judah for joy and for rejoicing, and for pleasant appointed seasons, and the truth and the peace they have loved.
