Hebrews 5:5-10; DRB;
5 So Christ also did not glorify himself, that he might be made a high priest: but he that said unto him: Thou art my Son, this day have I begotten thee. 6 As he saith also in another place: Thou art a priest for ever, according to the order of Melchisedech. 7 Who in the days of his flesh, with a strong cry and tears, offering up prayers and supplications to him that was able to save him from death, was heard for his reverence. 8 And whereas indeed he was the Son of God, he learned obedience by the things which he suffered: 9 And being consummated, he became, to all that obey him, the cause of eternal salvation. 10 Called by God a high priest according to the order of Melchisedech.
Hebrews 5:6-7; KJV;
6 As he saith also in another place, Thou art a priest for ever after the order of Melchisedec. 7 Who in the days of his flesh, when he had offered up prayers and supplications with strong crying and tears unto him that was able to save him from death, and was heard in that he feared;
Hebrews 5:6-7; Young's Literal Translation;
6 as also in another [place] He saith, `Thou [art] a priest -- to the age, according to the order of Melchisedek;' 7 who in the days of his flesh both prayers and supplications unto Him who was able to save him from death -- with strong crying and tears -- having offered up, and having been heard in respect to that which he feared,
May verse 7 means Melchisedec? I.e: Melchisedec who (Melchisedec) in the days of his flesh...etc.
I read an issue which says that the Tithes may be made from Melchizedek to Ibrahim (Abraham) or vise versa, i.e: from Ibrahim (Abraham) to Melchizedek. The same idea is here, (Who) may means Jesus or Melchizedek.
N.B, the crucifixion (death) already happened to Jesus the Christ.
