“For hee was yet in the loynes of his Father when Melchisedec met him.”
1611 King James Version (KJV)
Heb 7:10 For he was yet in the loins of his father, when Melchisedec met him. All Israel, kings and priests, though yet unborn, were represented in Abraham. Hence Levi paid tithes, and thus confessed the superiority of the priesthood of Melchizedek.
