The high priest here signifies Christ (Heb. 4:14), who died for our sins. Spiritually, the Old Testament saints had to remain in the city of refuge until Christ died; no ransom could have released them before the time of Christ’s death (v. 32). This was a refuge prior to direct salvation. In the Old Testament time Christ had not yet died, and those who fled into Him as their refuge had to wait there until He came and died on the cross. For the Old Testament saints, therefore, the refuge was like the sheepfold in John 10:1 (see note John 10:12 there).
Since Christ, our High Priest, has died, He is the refuge, not in the Old Testament sense but in the New Testament sense, to all His believers. This refuge is a matter of direct salvation. Before Christ’s death He was the refuge for the Old Testament saints, but now, after His death, He is our direct salvation. We who enter into Christ today may do so with the assurance that He has already died and that our sins have already been forgiven (Eph. 1:7; Col. 2:13).
