Isaias 29:9

And, after this, wishing to refute completely from the words of the prophets all these traditions of the elders among the Jews, He brought before them a saying, from Isaiah, which in the exact words is as follows: “And the Lord said, This people draws nigh to Me with their mouth,” etc.; and, as we said before, Matthew has not written out the prophetical saying in the very words. And, if it be necessary because of its use in the Gospel to interpret it according to our ability, we will take in addition the preceding passage which is, in my judgment, noted with advantage by us for the exposition of that passage in the Gospel which was taken from the prophet. …

And though these three things, when literally given way to weigh down the soul, and separate it from God, and bear it down to things earthly, yet it is very easy to avoid them, especially for us who are separated by so great a distance from all converse with this world, and who do not on any occasion have anything to do with those visible cares and drunkenness and surfeiting. …
