Abraham, the old man, was awoken from a deep sleep by a familiar voice. The voice was יהוה (YHWH) calling to him, "Abraham!" In the night, יהוה delivered unto him a stern command. Our father Abraham lay perfectly still, eyes fixed, awake until the early hours of the morning. Gathering two young men and his beloved son of promise, Isaac, he set out for the land of Moriah. As the days passed, Abraham rode on in silence, unable to move his lips to confess to his companions his purposes in leading them across the desert. During this time his face grew ever darker, eyes deep and empty. On the third day, he looked up and saw the mount in the distance, cursing it from the depths of his heart. "יהוה, You have brought into existence everything that is; nothing is beyond the depths of Your knowledge or the breadth of Your power. You do not forsake your people, yet you ask this thing of me. From the dust I beg you, that it may not be so." When father and son came to the place God had shown Abraham, he built an altar to the Lord. Clutching the knife at his side, his arm shook violently. As Isaac gazed at his father, his heart trembled, "The fire and the wood are here, but we have brought with us no lamb for a burnt offering." Abraham was unable to reply. "Father?" Isaac cried. Abraham answered him, "And yet this is what our Lord has required."As Abraham took the weapon, reaching out his hand to slaughter his son, an angel of the Lord called from Heaven, "Do not lay your hand on the boy. I know now that you fear God, since you have not withheld your only son." Abraham fell to the ground, gnashing his teeth with a loud moan. "You have counted my faith towards You as righteousness, and yet You see fit to test me and destroy my heart!" As they returned down the high mountain, Isaac saw a ram caught by the horns in a thicket. Gently, he placed his hand on the animal's head and set it free. From that day Abraham called his God אהיה אשר אהיה (Ehyeh asher Ehyeh), for the Lord stayed hidden behind Himself.

At night, the clouds hid the light of the moon as Abraham slept. A voice crept to his ear and spoke, "Abraham." The elderly man heard this as the voice of the Lord and, casting a protective arm across his wife, replied, "Here I am." And again God spoke. "Fetch your only son, Isaac, the one you love. Bring him to the land of Moriah, to a mountain that I will show you. There you will sacrifice him as a burnt offering to your God." In fury Abraham rose from his bed shouting, "Adversary, you are not the Lord, but הַשָׂטָן (ha-satan), come to oppose me! Has יהוה brought me out of Ur of the Chaldeans that I might curse my duty as a father and slay my child as the pagans do? Get behind me, accuser, for I will not allow you to obstruct the covenant the Lord has made with me for the blessing of all!"
