Let them alone,.... Have nothing to say, or do with them; do not mind their anger and resentment, their reproaches and reflections, nor trouble yourselves at the offence they have taken; if they will go, let them go; they are a worthless generation of men, who are not to be regarded, hearkened to, nor to be pleased; it matters not what they say of me, and of my doctrine:they be blind leaders of the blind; the people that hearken to them, and are followers of them, are "blind", as to any true sense of themselves, their state, and condition by nature; as to any spiritual, saving knowledge of God; as to any acquaintance with the Messiah, and the method of salvation by him; as to the Spirit of God, and the work of grace, regeneration, and sanctification upon the soul; as to the Scriptures of truth, and doctrines of the Gospel; and the "leaders" of them were as "blind" as they: by whom are meant the Scribes and Pharisees, the learned doctors and rabbins of the Jewish nation; who thought themselves very wise and knowing, yet they were blind also; and none more than they.
It was an old tradition among the Jews,"that there should be "blind teachers" at the time when God should have his tabernacle among them.''This was predicted, in Isa 42:19 and all such leaders and teachers are blind, who, notwithstanding their natural abilities, and acquired parts, are in a state of unregeneracy; and have nothing more than what they have from nature, or have attained to at school; and as apparently all such are, who lead men from Christ, to mere morality, and to a dependence upon their own righteousness for justification, which was the darling principle of the blind leaders in the text.
And if the blind lead the blind, both shall fall into the ditch; of ignorance and error, immorality and profaneness, distress, if not despair, temporal ruin and destruction; which was notoriously verified in the Jewish people, and their guides: and of eternal damnation, the lake which burns with fire and brimstone; what else can be expected?
