'Forever' in the Bible

but concerning the Son, "Your throne, O God, [is] {forever and ever}, and the scepter of righteous [is the] scepter of your kingdom.

just as also in another [place] he says, "You [are] a priest {forever} according to the order of Melchizedek,"

where Jesus, the forerunner for us, entered, [because he] became a high priest {forever} according to the order of Melchizedek.

For it is testified, "You [are] a priest {forever} according to the order of Melchizedek."

but he with an oath by the one who said to him, "The Lord has sworn and will not change his mind, 'You [are] a priest {forever}'"),

but he, because he continues {forever}, holds the priesthood permanently.

For the law appoints men [as] high priests who have weakness, but the statement of the oath, after the law, [appoints] a Son, who is made perfect {forever}.

Jesus Christ [is] the same yesterday and today and {forever}.

equip you with every good [thing] to do his will, carrying out in us [what is] pleasing before him through Jesus Christ, to whom [be] the glory {forever}. Amen.
