Then it shall be, when he maketh his sons to inherit that which he hath, that he may not make the son of the beloved firstborn before the son of the hated, which is indeed the firstborn:
1 Chronicles 5:2
For Judah prevailed above his brethren, and of him came the chief ruler; but the birthright was Joseph's:)
1 Chronicles 26:10
Also Hosah, of the children of Merari, had sons; Simri the chief, (for though he was not the firstborn, yet his father made him the chief;)
2 Chronicles 11:19-22
Which bare him children; Jeush, and Shamariah, and Zaham.
And after her he took Maachah the daughter of Absalom; which bare him Abijah, and Attai, and Ziza, and Shelomith.
And Rehoboam loved Maachah the daughter of Absalom above all his wives and his concubines: (for he took eighteen wives, and threescore concubines; and begat twenty and eight sons, and threescore daughters.)
And Rehoboam made Abijah the son of Maachah the chief, to be ruler among his brethren: for he thought to make him king.
2 Chronicles 21:3
And their father gave them great gifts of silver, and of gold, and of precious things, with fenced cities in Judah: but the kingdom gave he to Jehoram; because he was the firstborn.
For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren.
Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.
Lest there be any fornicator, or profane person, as Esau, who for one morsel of meat sold his birthright.
For ye know how that afterward, when he would have inherited the blessing, he was rejected: for he found no place of repentance, though he sought it carefully with tears.
