'Seventh' in the Bible

“Speak to all the people of the land and to the priests, saying, ‘When you fasted and mourned in the fifth and seventh months these seventy years [that you were in exile], was it actually for Me that you fasted?

“Thus says the Lord of hosts, ‘The fast of the fourth [month to mourn the breaching of Jerusalem’s walls], the fast of the fifth [month to mourn the temple’s destruction], the fast of the seventh [month to mourn Gedaliah’s assassination], and the fast of the tenth [month to mourn the siege of Jerusalem] will become times of joy and gladness and cheerful feasts for the house of Judah; so [to bring this about] love truth and peace.’
