Charles H. Spurgeon on Psalms 111:10

A good understanding have all they that do his commandments. They which do the commandments have a good understanding; not they which speak of the commandments, nor they which write of the commandments, nor they which preach of the commandments, but they which do the commandments, have a good understanding. The rest have a false understanding, a vain understanding, an understanding like that of the scribes and pharisees, which was enough to condemn them, but not to save them. —Henry Smith.
