“Wherefore Jesus also, that he might sanctify the people with his own blood, suffered without the gate.”
King James Version (KJV)
13:12 Wherefore Jesus also - Exactly answering those typical sin - offerings. Suffered without the gate - Of Jerusalem, which answered to the old camp of Israel. That he might sanctify - Reconcile and consecrate to God. The people - Who believe in him. By his own blood - Not those shadowy sacrifices, which are now of no farther use.
Heb 13:12 Wherefore Jesus also, that he might sanctify the people. In order to cleanse his people by becoming the complete atonement he was willing, as an accursed thing, a sin offering, to be led "without the gate" and to suffer there.
