John Wesley on Leviticus 4:6

Seven times - A number much used in scripture, as a number of perfection; and here prescribed, either to shew that his sins needed more then ordinary purgation, and more exercise of his faith and repentance, both which graces he was obliged to join with that ceremonial rite. Before the veil - The second veil dividing between the holy of holies, which is generally called the veil of the sanctuary.
