After all, the children of Israel were not wholly without merits. In a high degree they possessed qualities of extraordinary excellence. There were no incestuous relations among them, they were not evil-tongued, they did not change their names, they clung to the Hebrew language, never giving it up,[106] and great fraternal affection prevailed among them. If one happened to finish the tale of his bricks before his neighbors, he was in the habit of helping the others. Therefore God spake, "They deserve that I should have mercy upon them, for if a man shows mercy unto another, I have mercy upon him."[107] THE FAITHFUL SHEPHERD When Jethro bestowed his daughter Zipporah upon Moses as his wife, he said to his future son-in-law: "I know that thy father Jacob took his wives, the daughters of Laban, and went away with them against their father's will. Now take an oath that thou wilt not do the same unto me," and Moses swore not to leave him without his consent,[108] and he remained with Jethro, who made him the shepherd of his flocks. By the way he tended the sheep, God saw his fitness to be the shepherd of His people, for God never gives an exalted office to a man until He has tested him in little things. Thus Moses and David were tried as shepherds of flocks, and only after they had proved their ability as such, He gave them dominion over men. Moses watched over the flocks with loving care. He led the young animals to pasture first, that they might have the tender, juicy grass for their food; the somewhat older animals he led forth next, and allowed them to graze off the herbs suitable for them; and finally came the vigorous ones that had attained their full growth, and to them he gave the hard grass that was left, which the others could not eat, but which afforded good food for them. Then spake God, "He that understandeth how to pasture sheep, providing for each what is good for it, he shall pasture My people." Once a kid escaped from the flock, and when Moses followed it, he saw how it stopped at all the water courses, and he said to it: "Poor kid, I knew not that thou wast thirsty, and wast running after water! Thou art weary, I ween," and he carried it back to the herd on his shoulder. Then said God: "Thou hast compassion with a flock belonging to a man of flesh and blood! As thou livest, thou shalt pasture Israel, My flock."[109] Not only did Moses take heed that no harm should come to the herds under his charge, but he was also careful that they cause no injury to men. He always chose an open meadow as his pasturing place, to prevent his sheep from grazing in private estates.[110]
