Boyd’s Bible Dictionary:
Preparer of the way “within the veil”
(Heb. 6:19-20).
Concise Bible Dictionary:
Used symbolically of Christ, who has entered within the veil as the forerunner of the saints (Heb. 6:20). It is an allusion to those in high position in the East, who have men to run before them to clear the way, and to announce who is coming. In the case of Christ the reverse is the fact: the Lord has run before His servants; but the term necessarily implies that there are others who are following after.
