is the literal meaning of πρόδρομος (Hebrews 6:20), a precursor, one who not only goes before to a particular place, to lead or prepare the way, but who makes arrangements for those that follow. In this sense it in usually applied to John the Baptist, as the harbinger of Christ. But in the above text (the only one where it occurs in Scripture) it is spoken of Jesus, the high-priest of the new dispensation, as entering before his followers into the heavenly sanctuary, and making expiation of perpetual. efficacy for sinners (comp. John 14:2).
