I seek you with all my heart; do not let me stray from your commands. (NIV)
With my whole heart have I sought You, inquiring for and of You and yearning for You; Oh, let me not wander or step aside [either in ignorance or willfully] from Your commandments. [II Chron. 15:15.] (AMP)
With my whole heart have I sought thee: O let me not wander from thy commandments. (KJV)
