"Whatever God created has value." Even the animals and the insects that seem useless and noxious at first sight have a vocation to fulfil. The snail trailing a moist streak after it as it crawls, and so using up its vitality, serves as a remedy for boils. The sting of a hornet is healed by the house-fly crushed and applied to the wound. The gnat, feeble creature, taking in food but never secreting it, is a specific against the poison of a viper, and this venomous reptile itself cures eruptions, while the lizard is the antidote to the scorpion.[191] Not only do all creatures serve man, and contribute to his comfort, but also God "teacheth us through the beasts of the earth, and maketh us wise through the fowls of heaven." He endowed many animals with admirable moral qualities as a pattern for man. If the Torah had not been revealed to us, we might have learnt regard for the decencies of life from the cat, who covers her excrement with earth; regard for the property of others from the ants, who never encroach upon one another's stores; and regard for decorous conduct from the cock, who, when he desires to unite with the hen, promises to buy her a cloak long enough to reach to the ground, and when the hen reminds him of his promise, he shakes his comb and says, "May I be deprived of my comb, if I do not buy it when I have the means." The grasshopper also has a lesson to teach to man. All the summer through it sings, until its belly bursts, and death claims it. Though it knows the fate that awaits it, yet it sings on. So man should do his duty toward God, no matter what the consequences. The stork should be taken as a model in two respects. He guards the purity of his family life zealously, and toward his fellows he is compassionate and merciful. Even the frog can be the teacher of man. By the side of the water there lives a species of animals which subsist off aquatic creatures alone. When the frog notices that one of them is hungry, he goes to it of his own accord, and offers himself as food, thus fulfilling the injunction, "If thine enemy be hungry, give him bread to eat; and if he be thirsty, give him water to drink."[192] The whole of creation was called into existence by God unto His glory,[193] and each creature has its own hymn of praise wherewith to extol the Creator. Heaven and earth, Paradise and hell, desert and field, rivers and seas—all have their own way of paying homage to God. The hymn of the earth is, "From the uttermost part of the earth have we heard songs, glory to the Righteous." The sea exclaims, "Above the voices of many waters, the mighty breakers of the sea, the Lord on high is mighty."
