'Fifth' in the Bible

and to speak to the priests of the house of Yahweh of Armies, and to the prophets, saying, "Should I weep in the fifth month, separating myself, as I have done these so many years?"

"Speak to all the people of the land, and to the priests, saying, 'When you fasted and mourned in the fifth and in the seventh month for these seventy years, did you at all fast to me, really to me?

Thus says Yahweh of Armies: "The fasts of the fourth fifth, seventh, and tenth months shall be for the house of Judah joy and gladness, and cheerful feasts. Therefore love truth and peace."
