Hebrews. 5:6 “you are a priest forever according to the order of Melchizedek” This is a quote from Ps. 110:4. This Psalm is unique in the fact that it specifically gives the Messiah both a priestly and a kingly office (cf. Zech. 4:3, 11–14; 6:13). We learn from the Dead Sea Scrolls that the Essenes were expecting two Messiahs, one royal and one priestly. Jesus fulfilled both offices. As a matter of fact, He fulfills all three OT anointed offices: prophet, priest and king (cf. Hebrews 1:1–3)
