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 such cruelty will, if circumstances be favourable, be cruel to his fellow-creatures.
