'Lamb' in the Bible

Isaac addressed his father Abraham: "My father!" "I'm here, my son," Abraham replied. Isaac asked, "The fire and the wood are here, but where's the lamb for the burnt offering?"

Abraham answered, "God will provide himself the lamb for the burnt offering, my son."

Jacob responded, "You don't have to give me anything. Just do this for me: Let me tend your flock again and watch over it. Let me walk among your flocks today and remove every speckled or spotted sheep, along with every black lamb, and let me do the same with the speckled and spotted goats. These will be my wages.
