• ""built their nests" in the tree: the Greek word has no such meaning; the word merely means "to settle or rest upon" anything for a longer or shorter time; nor is there any occasion to suppose that the expression "fowls of the air" denotes any other than the smaller insessorial kinds -- linnets, finches, etc."
