Covenant to Be a Priest Like Melchizedek. This covenant is expressed at Psalm 110:4, and the writer of the Bible book of Hebrews applies it to Christ at Hebrews 7:1-3, 15-17. It is a covenant made by Jehovah with Jesus Christ alone. Jesus apparently referred to it when making a covenant for a kingdom with his followers. (Lu 22:29)

Jesus’ Covenant With His Followers. On the night of Nisan 14, 33 C.E., after celebrating the Lord’s Evening Meal Jesus made this covenant with his faithful apostles. To the 11 faithful apostles he promised that they would sit on thrones. (Lu 22:28-30; compare 2Ti 2:12.) Later, he showed that this promise extended to all spirit-begotten ‘conquerors.’ (Re 3:21; see also Re 1:4-6; 5:9, 10; 20:6.) On the day of Pentecost he inaugurated this covenant toward them by the anointing with holy spirit of those disciples present in the upper room in Jerusalem. (Ac 2:1-4, 33) Those who would stick with him through trials, dying his kind of death (Php 3:10; Col 1:24), would reign with him, sharing his Kingdom rule. The covenant remains operative between Jesus Christ and these associate kings forever.​—Re 22:5.
