1 Corinthians 15:22

“For as in Adam all die, etc.] The apostle here shows who he meant in the former verse, by the one man the cause of death, and by the other the author of the resurrection of the dead, and that he intended Adam and Christ; all men were in Adam seminally, as the common parent of human nature, in such sense as Levi was in the loins of Abraham when Melchizedek met him, and in him paid tithes unto him; and they were all in him representatively, he being the federal head of all his posterity, and so a type and figure of Christ that was to come; and being in him, they all sinned in him, and so died in him, the sentence of death passed on them in him; they became subject to a corporeal death, which…”
