Genesis Chapter 25 Verse 21And Isaac intreated the LORD for his wife, because she [was] barren: and the LORD was intreated of him, and Rebekah his wife conceived.

And it came to pass after the death of Abraham, that God blessed his son Isaac; and Isaac dwelt by the well Lahairoi.

Now these [are] the generations of Ishmael, Abraham's son, whom Hagar the Egyptian, Sarah's handmaid, bare unto Abraham:

And these [are] the names of the sons of Ishmael, by their names, according to their generations: the firstborn of Ishmael, Nebajoth; and Kedar, and Adbeel, and Mibsam,

And Mishma, and Dumah, and Massa,

Hadar, and Tema, Jetur, Naphish, and Kedemah:

These [are] the sons of Ishmael, and these [are] their names, by their towns, and by their castles; twelve princes according to their nations.

And these [are] the years of the life of Ishmael, an hundred and thirty and seven years: and he gave up the ghost and died; and was gathered unto his people.

And they dwelt from Havilah unto Shur, that [is] before Egypt, as thou goest toward Assyria: [and] he died in the presence of all his brethren.

And these [are] the generations of Isaac, Abraham's son: Abraham begat Isaac:

And Isaac was forty years old when he took Rebekah to wife, the daughter of Bethuel the Syrian of Padanaram, the sister to Laban the Syrian.

And the children struggled together within her; and she said, If [it be] so, why [am] I thus? And she went to enquire of the LORD.

And the LORD said unto her, Two nations [are] in thy womb, and two manner of people shall be separated from thy bowels; and [the one] people shall be stronger than [the other] people; and the elder shall serve the younger.

And when her days to be delivered were fulfilled, behold, [there were] twins in her womb.

And the first came out red, all over like an hairy garment; and they called his name Esau.

And after that came his brother out, and his hand took hold on Esau's heel; and his name was called Jacob: and Isaac [was] threescore years old when she bare them.

And the boys grew: and Esau was a cunning hunter, a man of the field; and Jacob [was] a plain man, dwelling in tents.

And Isaac loved Esau, because he did eat of [his] venison: but Rebekah loved Jacob.

And Jacob sod pottage: and Esau came from the field, and he [was] faint:

And Esau said to Jacob, Feed me, I pray thee, with that same red [pottage]; for I [am] faint: therefore was his name called Edom.

And Jacob said, Sell me this day thy birthright.
