Psalms 119:2, 7, 10, 34, 58, 69, 80, 145

Blessed and favored by God are those who keep His testimonies, And who [consistently] seek Him and long for Him with all their heart.

I will give thanks to You with an upright heart, When I learn [through discipline] Your righteous judgments [for my transgressions].

With all my heart I have sought You, [inquiring of You and longing for You]; Do not let me wander from Your commandments [neither through ignorance nor by willful disobedience]. [2 Chr 15:15]

Give me understanding [a teachable heart and the ability to learn], that I may keep Your law; And observe it with all my heart. [Prov 2:6; James 1:5]

I sought Your favor with all my heart; Be merciful and gracious to me according to Your promise.

The arrogant have forged a lie against me, But I will keep Your precepts with all my heart.

May my heart be blameless in Your statutes, So that I will not be ashamed.

¶I cried with all my heart; answer me, O LORD! I will observe Your statutes.
