All fowles that creepe] As fowles they should flye; but creeping basely on the ground, they may note the ambiguous, and earthly-minded disposition of worldly men.
upon all foure] Some things that flye have foure feete; some have more, as hornets, bees, flies; and those that have more feet then two, have no fewer then foure; and those that have more then two are excluded from use of meat (as uncleane), when they who have foure are mentioned in the prohibition of meats. See vers. 42.
