'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 happened at the seventh time, that he said, "Behold, a small cloud, like a man's hand, is rising out of the sea." He said, "Go up, tell Ahab, 'Get ready and go down, so that the rain doesn't stop you.'"

They encamped one over against the other seven days. So it was, that in the seventh day the battle was joined; and the children of Israel killed one hundred thousand footmen of the Syrians in one day.
