Similar commands we meet with in Leviticus 19:19. Certainly there must have been somewhat of a spiritual meaning couched under these things; and what more likely to be intended by it, than that the heart should not be sown with diverse doctrine's: that the man who plows spiritually, should not mingle anything idolatrous with the true worship of the GOD of Israel: and put not on the woollen garment of his own poor righteousness, with the linen robe of GOD'S righteousness. Precious JESUS! do I not see in this, a clear reference that the Souls of thy people, may never mingle ought of their own, with the perfect and complete robe of thy salvation; which, like the garment that covered thy sacred body in the days of thy flesh, was without seam, wove from the top throughout. John 19:23. And LORD, far be it from me, to make fringes to thy vesture, or fancy my poor offerings can add to thy complete glory, in the great work of salvation! 1 Corinthians 3:11-13.
