But thou shalt: The extirpation of any species of birds, whether edible or birds of prey, is often attended with serious consequences, and is always productive of evil; to prevent which was the object of this law. Palestine is situated in a climate producing poisonous snakes and scorpions, and between deserts and mountains, from which it would be inundated by them, as well as with immense swarms of flies, locusts, and mice, if the birds which feed upon them were extirpated. In a moral point of view, it may have been intended to inculcate a spirit of mercy and kindness, and to prevent the exercise of cruelty even towards a sparrow; for he who is guilty of such cruelty will, if circumstances be favourable, be cruel to his fellow-creatures.
