Psalms 51:6 - Exposition

Behold, thou desirest truth in the inward parts (comp. Job 38:36 ). God requires not merely such purity as might be attained by the use of legal and ritual methods; but true inward purity of thought and heart, which is a very different matter. And in the hidden part thou shalt make me to know wisdom; rather, do thou make me. An optative, according to Professor Cheyne. The meaning is, "As nothing will content thee but this perfect, inward purity, do thou give me into my heart its fundamental principle-wisdom, or the fear of God."
