What Does Deuteronomy 10:7 Mean?

And Eleazar his son ministered in the priest's office in his stead. The priestly succession from Aaron to Eleazar demonstrates both continuity and limitation of the old covenant ministry. Continuity because the priesthood continues despite individual death; limitation because succession is necessary.

The phrase in his stead indicates replacement - Eleazar takes Aaron's place because Aaron can no longer serve. This revolving succession of priests illustrates the temporary nature of the Aaronic priesthood. Each generation requires new priests as the old die.

Reformed theology sees this succession as revealing the priesthood's inadequacy to provide permanent mediation. If the Aaronic priesthood could perfect worshipers, no succession would be needed. The need for replacement priests testified that the old covenant system could not provide ultimate reconciliation between God and humanity.

Christ's priesthood requires no succession - He ever lives to make intercession (Hebrews 7:25). His resurrection guarantees permanent, unchanging advocacy for believers. We need no new mediator because the one Mediator never dies.
