My mouth shall speak of wisdom; and the meditation of my heart shall be of understanding.
Read Chapter 49
Augustine of Hippo
AD 430
4. And what is it they are now to hear? "My mouth shall speak of wisdom, and the meditation of my hear understanding" (ver. 3). And this repetition is perhaps made, lest perchance if he had said only "my mouth," thou shouldest suppose that one spake to thee who had understanding but in his lips. For many have understanding in their lips, but have not in their heart, of whom the Scripture saith, "This people honoureth me with their lips, but their heart is far from me." What saith he then who speaketh to thee? when he hath said, "My mouth shall speak of wisdom," in order that thou mayest know that what is poured forth from the mouth floweth from the bottom of the heart, he hath added, "And the meditation of my heart of understanding."
