“יהוה, Elohim of the heavens, who took me from my father’s house and from the land of my relatives, and who spoke to me and swore to me, saying, ‘To your seed I give this land,’ He sends His messenger before you, and you shall take a wife for my son from there.
See, I am ready to come to you for the third time. And I shall not be a burden to you, for I do not seek yours, but you. For the children should not lay up for the parents, but the parents for the children.
then it shall be, on the day he makes his sons to inherit his possessions, he is not allowed to treat the son of the beloved wife as first-born in the face of the son of the unloved, who is truly the first-born.
