Hebrews 6:20
King James Bible
Whither the forerunner is for us entered,
even Jesus, made an high priest for ever after the order of
Melchisedec.
Ezra 7:1-4
...
Zadok, The son of Ahitub, son of Amaryah, son of Azaryah, son of Mirayoth,
son of Zerachyah, son of Uzzi, son of Bukki, son of Avishua, son of
Phineas
(CLV) Num 25:11
Phinehas, son of Eleazar, son of Aaron the priest, reversed My fury from on the sons of Israel in his zeal- for My jealousy in their midst so I did not finish the sons of Israel in My jealousy.
(CLV) Num 25:12
Therefore say: Behold Me giving to him My covenant of peace;
(CLV) Num 25:13
it will be his and his seed's after him, the covenant of an eonian priesthood, in as much as he was zealous for his Elohim and made a propitiatory shelter over the sons of Israel.
So who passed the Zadok Priesthood to Yahshua?
