Some have thought that a young calf being appointed for the sin-offering of Aaron, was to remind him of his former transgression in making the golden calf: that thereby he might never lose sight of his own unworthiness, while the LORD had called him to such an exalted rank as the High Priest before the people. Exodus 32:1-6. Reader! do not overlook the preciousness of thy High Priest, in this relation, but read what Paul saith, Hebrews 7:26-27.
