Jacob said: Swear therefore to me. Esau swore to him, and sold his first birthright.
And Jacob said, Swear to me this day; and he sware unto him: and he sold his birthright unto Jacob.
Jacob said, Swear to me today [that you are selling it to me]; and he swore to [Jacob] and sold him his birthright.
And Jacob said, Swear to me first; and he sware unto him: and he sold his birthright unto Jacob.
Jacob said, “Give me your word today.” And he did. He sold his birthright to Jacob.
Jacob said, "So then, swear to me." Esau swore to him, and he sold his right of the firstborn.
