Hebrews 7:10

ἔτι γὰρ ἐν τῇ ὀσφύϊ τοῦ πατρὸς ἦν, ὅτε συνήντησεν αὐτῷ ὁ Μελχισεδέκ.

eti gar en tē osphyi toy patros ēn, ote synēntēsen aytō o Melchisedek.

King James Version (KJV)

For he was yet in the loins of his father, when Melchisedec met him.

Modern English

because when Melchizedek met Abraham, Levi was still in the body of his ancestor.
