“Now what do you suppose this to be a type of, that a command was given to Israel, that men of the greatest wickedness should offer a heifer, and slay and burn it, and that then boys should take the ashes, and put these into vessels, and bind round a stick purple wool along with hyssop, and that thus the boys should sprinkle the people one by one, in order that they might be purified from their sins? Consider how he speaks to you with simplicity. The calf is Jesus; the sinful men offering it are those who led Him to the slaughter. But now the men are no longer guilty, are no longer regarded as sinners. And the boys that sprinkle are those that have proclaimed to us the remission of sins and purification of heart. To these He gave authority to preach the gospel, being twelve in number, corresponding to the twelve tribes of Israel. But why are there three boys that sprinkle? To correspond to Abraham, and Isaac, and Jacob, because these were great with God. And why was the wool [placed] upon the wood? Because by wood Jesus holds His kingdom, so that [through the cross] those believing on Him shall live forever. But why was hyssop joined with the wool? Because in His kingdom the days will be evil and polluted in which we shall be saved, [and] because he who suffers in body is cured through the cleansing efficacy of hyssop. And on this account the things which stand thus are clear to us, but obscure to them, because they did not hear the voice of the Lord.”[47] Chapter ix. discusses the spiritual meaning of circumcision. The closing portion of the chapter is as follows: “Yea, the Egyptians also practise circumcision. Learn then, my children, concerning all things richly, that Abraham, the first who enjoined circumcision, looking forward in spirit to Jesus, practised that rite, having received the mysteries of the three letters. For [the Scripture] saith, ‘And Abraham circumcised ten and eight and three hundred men of his household.’ What then was the knowledge given to him in this? Learn the eighteen first, and then the three hundred. The ten and the eight are thus denoted--ten by I, and eight by H. You have [the initials of] Jesus, and because the cross was to express the grace [of our redemption] by the letter T, he says also, ‘three hundred.’ He signifies, therefore, Jesus by two letters, and the cross by one. He knows this, who has put within us the engrafted gift of His doctrine. No one has been admitted by me to a more excellent piece of knowledge than this, but I know that ye are worthy.”[48] The tenth chapter, which treats of the _Spiritual Significance of the Precepts of Moses Respecting Different Kinds of Food_, can be quoted only in part; portions of it are unfit for the public eye, and yet these portions, gross as they are, are solemnly set forth as an exegesis of Scripture. The chapter follows here, except the grosser sentences:
