'Seventh' in the Bible
All the men of Israel assembled themselves to King Solomon at the feast, in the month Ethanim, which is the seventh month.
It came about at the seventh time, that he said, “Behold, a cloud as small as a man’s hand is coming up from the sea.” And he said, “Go up, say to Ahab, ‘Prepare your chariot and go down, so that the heavy shower does not stop you.’”
So they camped one over against the other seven days. And on the seventh day the battle was joined, and the sons of Israel killed of the Arameans 100,000 foot soldiers in one day.
