31 And Jacob said to him: Sell me thy first birthright. 32 He answered: Lo I die, what will the first birthright avail me? 33 Jacob said: Swear therefore to me. Esau swore to him, and sold his first birthright. 34 And so taking bread and the pottage of lentils, he ate, and drank, and went his way; making little account of having sold his first birthright.
1 And when a famine came in the land, after that barrenness which had happened in the days of Abraham, Isaac went to Abimelech king of the Palestines to Gerara. 2 And the Lord appeared to him and said: Go not down into Egypt, but stay in the land that I shall tell thee. 3 And sojourn in it, and I will be with thee, and will bless thee: for to thee and to thy seed I will give all these countries, to fulfill the oath which I swore to Abraham thy father. 4 And I will multiply thy seed like the stars of heaven: and I will give to thy posterity all these countries: and in thy seed shall all the nations of the earth be blessed. 5 Because Abraham obeyed my voice, and kept my precepts and commandments, and observed my ceremonies and laws.
6 So Isaac abode in Gerara.
