Genesis 4:4

Abel, he also brought of the firstlings of his flock - Dr. Kennicott contends that the words he also brought, hebi gam hu , should be translated, Abel brought it also, i.e. a minchah or gratitude offering; and beside this he brought of the first-born ( mibbechoroth ) of his flock, and it was by this alone that he acknowledged himself a sinner, and professed faith in the promised Messiah. To this circumstance the apostle seems evidently to allude, Hebrews 11:4 : By Faith Abel offered , a More or Greater sacrifice; not a more excellent, (for this is no meaning of the word ), which leads us to infer, according to Dr. Kennicott, that Abel, besides his minchah or gratitude offering, brought also , a victim, to be slain for his sins; and this he chose out of the first-born of his flock, which, in the order of God, was a representation of the Lamb of God that was to take away the sin of the world; and what confirms this exposition more is the observation of the apostle: God testifying , of his Gifts, which certainly shows he brought more than one. According to this interpretation, Cain, the father of Deism, not acknowledging the necessity of a vicarious sacrifice, nor feeling his need of an atonement, according to the dictates of his natural religion, brought a minchah or eucharistic offering to the God of the universe. Abel, not less grateful for the produce of his fields and the increase of his flocks, brought a similar offering, and by adding a sacrifice to it paid a proper regard to the will of God as far as it had then been revealed, acknowledged himself a sinner, and thus, deprecating the Divine displeasure, showed forth the death of Christ till he came. Thus his offerings were accepted, while those of Cain were rejected; for this, as the apostle says, was done by Faith, and therefore he obtained witness that he was righteous, or a justified person, God testifying with his gifts, the thank-offering and the sin-offering, by accepting them, that faith in the promised seed was the only way in which he could accept the services and offerings of mankind. Dr. Magee, in his Discourses on the Atonement, criticises the opinion of Dr. Kennicott, and contends that there is no ground for the distinction made by the latter on the words he also brought; and shows that though the minchah in general signifies an unbloody offering, yet it is also used to express both kinds, and that the minchah in question is to be understood of the sacrifice then offered by Abel. I do not see that we gain much by this counter-criticism. See Genesis 4:7.
