TSK · Deuteronomy 21:17

Abraham gave all that he had to Isaac,

"Reuben, you are my firstborn, my might, and the beginning of my strength; excelling in dignity, and excelling in power.

For Judah prevailed above his brothers, and of him came the prince; but the birthright was Joseph's:)

He struck also all the firstborn in their land, the first fruits of all their manhood.
