'Months' in the Bible

“Ask all the people of the land and the priests: When you fasted and lamented in the fifth and in the seventh months for these 70 years, did you really fast for Me?

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?

"This is what the LORD of the Heavenly Armies says: "The fasts that occur in the fourth, fifth, seventh, and tenth months will be joyful and glad times for the house of Judah, replete with cheerful festivals. Therefore, love truth and peace.'"
