Why did God choose to bestow the birthright blessing to Joseph? Deuteronomy 33:16 provides the key to the answer. Moses writes, "Let the blessing come on the head of Joseph, and on the crown of the head of him who was separate from his brothers."
God honored Joseph because he "was separate from his brothers." He was separate in that he alone remained faithful to his God. Conspicuous by their absence are the names of Joseph's brothers from the Faith Chapter. Hebrews 11 does not mention Reuben, Judah, Dan, Gad, or any other of Jacob's sons. Verse 22 emphasizes Joseph's faithfulness: "By faith Joseph, when he was dying, made mention of the departure of the children of Israel, and gave instructions concerning his bones" (Genesis 50:22-26)
Allaying his brothers' fears of retribution and revenge, Joseph explained his understanding that God had placed him in power in Egypt "to preserve a posterity for you in the earth, and to save your lives by a great deliverance" (Genesis 45:7). To his dying day, he never broke faith with his brothers: As recorded in Genesis 50:20-21, he reassures them of their well-being after their father's death:
But as for you, you meant evil against me; but God meant it for good, in order to bring it about as it is this day, to save many people alive. Now therefore, do not be afraid; I will provide for you and your little ones.
Nor did he ever break faith with his God. Dying, he reminded his brothers that God would bring their posterity out of Egypt, restoring them "to the land of which He swore to Abraham, to Isaac, and to Jacob" (Genesis 50:24).
The two sons of Joseph received the birthright blessings because their father was separate, ethically and morally, from his perfidious, scheming brothers. His brothers exhibited few scruples concerning killing Joseph, forswearing murder only when they saw the opportunity to profit from selling him into slavery. Compounding their despicable and abject turpitude, they darkened their father's days by sustaining the ruse of Joseph's death for more than a decade. See Genesis 34 for a fine example of cunning deception, ruthless murder, and rapacious greed on the part of Simeon and Levi in the affair of their sister Dinah with Hamor, a Hivite prince living in Canaan at that time.
What a paradox! Today, Ephraim and Manasseh have used the wealth and influence God gave them because of Joseph's faithfulness to push on Gentile nations a way of life totally contrary to God's way. Rather than separating from the ways of this world, as their father Joseph did, modern-day Ephraim and Manasseh push globalism, another term for the Babylonian system of "get," on the whole world. Sifted among the nations, Joseph subverts those around him rather than serving as an example of godliness to the Gentiles.
