Are ye also yet without understanding? - Jesus appeals, in explaining this, to their common sense; and he wonders that they had not yet learned to judge the foolish traditions of the Jews by the decisions of common sense and by his own instructions.

Are ye also yet without understanding? - The word ακμη, which we translate yet, should be here rendered still: Are ye still void of understanding? and the word is used in this sense by several Greek writers. The authorities which have induced me to prefer this translation may be seen in Kypke.

And Jesus said,.... As wondering at, and as being displeased with, and as reproving them for their dulness and ignorance:

are ye also yet without understanding? you, my disciples, as well as the Scribes and Pharisees; you, who have been with me so long, who have heard so many discourses from me, who for so long a time have been instructed by me, both in private, and in public; and yet do not understand what is so plain and easy, that has nothing of difficulty in it, but what might easily be accounted for.

And Jesus said, Are ye also yet without understanding?

16. And Jesus said, Are ye also yet without understanding?-Slowness of spiritual apprehension in His genuine disciples grieves the Saviour: from others He expects no better (Mt 13:11).

15:10-20 Christ shows that the defilement they ought to fear, was not from what entered their mouths as food, but from what came out of their mouths, which showed the wickedness of their hearts. Nothing will last in the soul but the regenerating graces of the Holy Spirit; and nothing should be admitted into the church but what is from above; therefore, whoever is offended by a plain, seasonable declaration of the truth, we should not be troubled at it. The disciples ask to be better taught as to this matter. Where a weak head doubts concerning any word of Christ, an upright heart and a willing mind seek for instruction. It is the heart that is desperately wicked, Jer 17:9, for there is no sin in word or deed, which was not first in the heart. They all come out of the man, and are fruits of that wickedness which is in the heart, and is wrought there. When Christ teaches, he will show men the deceitfulness and wickedness of their own hearts; he will teach them to humble themselves, and to seek to be cleansed in the Fountain opened for sin and uncleanness.
