For when Moses had spoken every precept
Contained in the decalogue, in the book of the covenant, everyone of the precepts in ( Exodus 22:1-23:33 ) for this is to be understood of the written law, and not of the oral law the Jews talk of, which they say Moses first delivered by word of mouth to Aaron, then to his two sons, Eleazar and Ithamar, then to the seventy elders of Israel, and then to the whole congregation; so that Aaron heard it four times, his sons thrice, the seventy elders twice, and all Israel once F7: but this is the written law which he spoke audibly, and in a known language,
to all the people according to the law;
which God gave him on the Mount: this may instruct persons concerned in the public ministry, to speak out plainly and clearly the whole counsel of God, to all to whom they are sent, according to the word of God, which is the rule of faith and practice:
he took the blood of calves, and of goats;
in the relation of this affair in ( Exodus 24:5 ) which is referred to, only mention is made of oxen, bullocks, or heifers, here called calves, which were sacrificed for peace offerings, and not of goats; though perhaps they may be intended by the burnt offerings there spoken of, since they were sometimes used for burnt offerings, ( Leviticus 1:10 ) . The Syriac version only reads, "he took the blood of an heifer"; and the Arabic version, "he took the blood of calves"; but all the copies, and other versions, read both. "With water, and scarlet wool, and hyssop"; neither of these are mentioned in ( Exodus 24:1-18 ) , but since sprinkling is there said to be used, and blood and water mixed together, and scarlet and hyssop were used in sprinkling, as in sprinkling the leper, and the unclean house, ( Leviticus 14:5-7 Leviticus 14:49-51 ) the apostle justly concludes the use of them here; the blood, with water, was typical of the blood and water which sprung from the side of Christ pierced on the cross, the one signifying justification by him, the other sanctification; the scarlet wool, which is originally white, but becomes scarlet by being dyed, may denote the native purity of Christ, and his bloody sufferings and death; the hyssop may signify his humility, and the purging virtue of his blood, and the sweet smelling savour of his person, righteousness, and sacrifice. The apostle calls scarlet, scarlet wool; though whenever the word is used in the Jewish laws of the Old Testament, wool is not expressed, but it is always intended; for it is a rule with the Jews F8, that
``the blue, which is spoken of in every place, is wool dyed of a sky colour; purple is wool dyed red, and scarlet is wool dyed in scarlet.''And sprinkled both the book, and all the people.
