Psalms 69:5 - Exposition

O God, thou knowest my foolishness (see Psalms 38:5 ). According to the teaching both of the Old Testament (Proverbs, passim ) and of the New ( Mark 7:22 ; Romans 1:21 , Romans 1:22 ; Galatians 3:1 , etc.), folly is a form of sin. And my sins are not hid from thee. The rebuke of Nathan and the death of his child ( 2 Samuel 12:7-19 ) had fully convinced David of this. Thenceforward his sins were ever before him ( Psalms 51:3 ), continually confessed by him, and felt to be as well known to God as to himself. Compare the opening of Psalms 139:1-24 :, "Lord, thou hast searched me, and known me. Thou knowest my downsitting and mine uprising, thou understandest my thought afar off. Thou compassest my path and my lying down, and art acquainted with all my ways. For there is not a word in my tongue, but, lo, O Lord, thou knowest it altogether" ( Psalms 139:1-4 ).
