Genesis 25:29-34

29One day, Jacob was cooking a meal. Esau came back from the country. He was very hungry.

30He said to Jacob ‘Quick, let me have some of that red food! I am very hungry.’ (That is why he was also called Edom.)

31Jacob said, ‘You must first sell me your birthright.’

32Esau said, ‘Look, I am so hungry that I will die. Then my birthright will not help me at all!’

33Jacob said, ‘First, make a serious promise to me.’ So Esau promised to sell his birthright to Jacob.

34Then Jacob gave Esau some bread and the soup made from grains. Esau ate the food and he drank. Then he got up and he left. In that way, Esau showed that he did not think that his birthright was important.
