John Wesley on Numbers 19:4

Before the tabernacle - Or, towards the tabernacle, standing at a good distance from it, even without the camp, yet turning and looking towards it. For here is no intimation that he went into the camp before this work was done, but rather the contrary is implied, Nu 19:7. And because being defiled by this work he could not come near the tabernacle, it was sufficient for him to turn and look towards it. This signified his presenting this blood before the Lord by way of atonement for his and the people's sins, and his expectation of acceptance and pardon only from God, and from his mercy - seat in the tabernacle. And this typified the satisfaction that was made to God, by the death of Christ, who by the eternal Spirit offered himself without spot to God, and did as it were sprinkle his own blood before the sanctuary, when he said, Into thy hands I commend my spirit!
