פירוש על משלי 26:2

Like a wandering sparrow that wanders and like a swallow that returns to its nest, so...

will a vain curse come home to the one who uttered it with his mouth.

swallow Heb. דרור. This is the bird known as arondele in Old French, [hirondelle in modern French, schwalbe in German,] which is called דרור, because it lives (דר) in a house as in a field.
