sanctifieth] By (sanctifie) here understand not onely the renewing of our nature, but also our justification. See Chap. 9. 9. & 10. 10. Ephesians 5:26. by both which the Prince of our salvation brings sonnes unto glory. Or Christs consecrating us unto his Father, Revelation 1:6.
of one] That is, of one masse or lump, or of the same nature. It is conceived by some that this rule is taken from the manner of sanctifying under the Old Testament; under which the high Priest and those whom he sanctified, were of one and the same nature; and so the firstlings and first fruits, were of the same nature with the whole Flock and Crop, which was sanctified in them.
brethren] That is, to reckon himselfe amongst them as one of the same nature and condition; for in those texts afterwards alleadged, he doth not in expresse words call them brethren, but onely imply it.
