23. That mayest thou offer ... The passage should be rendered thus. 'If thou offer it either for a free-will offering or for a vow, it shall not be accepted.' This sacrifice being required to be "without blemish," symbolically implied that the people of God were to dedicate themselves wholly, with sincere purpose of heart; and its being required to be 'perfect to be accepted,' led them typically to Him without whom fie sacrifice could be offered acceptable to God.
