Vulg. 1 Kgs 18:44

In septima autem vice, ecce nubecula parva quasi vestigium hominis ascendebat de mari. Qui ait: Ascende, et dic Achab: Junge currum tuum et descende, ne occupet te pluvia.

And at the seventh time: Behold a little cloud arose out of the sea like a man's foot. And he said: Go up, and say to Achab: Prepare thy chariot, and go down, lest the rain prevent thee.
