창세기 5:33의 Dibur_hamatchil

Another thing, the Book of Adam's Descendants was passed before him. He saw David's portion of life would be three hours. He said, "Master of the world, this should not be decreed! A thought has come to me." He [Adam] said to him, "How many are my years?" God said, "1,000 years." Adam said, "Can I give some as a gift?" God said, "Yes." Adam said, "I will give him 70 years to be his fate." What did Adam do? He brought a contract and wrote on it a contract of gift; and it was executed by God, Metatron, and Adam. Adam said, "Master of the World, good looks are his, kingship, and songs of praise have I given him in my gift of 70 years of his life; and he will sing before you. And this is written where it says "behold I have come" in the book I have written [Tehillim 92].
