I cried with my whole heart - This commences a new division of the psalm, indicated by the Hebrew letter Koph (ק q ), answering to our letter “k.” The expression “I cried with my whole heart” means that he did it earnestly, fervently. He had no divided wishes when he prayed. Not always is this so, even with good people. They sometimes offer a form of prayer, that they may be spiritually-minded, when their hearts are intensely worldly, and they would be unwilling to be otherwise; or that religion may be revived, when their hearts have no lively interest in it, and no wish for it; or that they may live wholly to God, when they are making all their arrangements to live for the world, and when they would be greatly disappointed if God should take means to make them live entirely to him; or that they may be humble, childlike, sincere, when they have no wish to be any otherwise than they are now, and when they would regard it as an affront if it should be assumed by any that they are not so now, and if they were exhorted to change their course of life. Often it would be a great surprise - perhaps grief - even to professedly religious persons, if God should answer their prayers, and should make them what they professedly desire to be, and what they pray that they may be. See the notes at Psalm 9:1; compare Psalm 111:1; Psalm 138:1; Psalm 119:2, Psalm 119:10, Psalm 119:34, Psalm 119:58, Psalm 119:69; Jeremiah 24:7.
I will keep thy statutes - It is my purpose and desire to keep thy law perfectly.
