ISB ~ Hebrews 7 v17

You are a priest for ever:The words of Ps 110:4.

• This is the oath of perpetual priesthood that Yahweh swore to confer on the royal heir of David. It has provisional reference to Solomon, who exercised a limited priestly ministry (1 Kings 3:15; 8:63; 9:25), just as David had done (2 Sam 6:12-19). But only the Davidic Messiah, risen to an immortal life (Heb 7:16), qualifies for the everlasting priesthood envisioned by the psalm (Heb 7:23-25).
