23 Keep your heart with all diligence; for out of it [are] the issues of life.

26 My son, give Me your heart, and let your eyes watch My ways.

1 My son, forget not My law; but let your heart keep My commandments;2 for they shall add length of days, and long life, and peace, to you.

45 A good man out of the good treasure of his heart brings forth the good. And an evil man out of the evil treasure of his heart brings forth the evil. For out of the abundance of the heart his mouth speaks.

10 Create in me a clean heart, O God, and renew a right spirit within me.

8 Blessed [are] the pure in heart! For they shall see God.

23 Search me, O God, and know my heart; try me, and know my thoughts,24 and see if [any] wicked way [is] in me; and lead me in the way everlasting.

2 Examine me, O LORD, and prove me; purify my heart and my mind.3 For Your loving-kindness [is] before my eyes; and I have walked in Your truth.

3 You have proved my heart; You have visited [me] in the night; You have tried me, and You will find nothing; my thoughts do not pass beyond my mouth.4 Concerning the works of men, by the words of Your lips, I am kept [from] the paths of the destroyer.5 My steps have been held in Your paths, [so that] my footsteps have not slipped.

7 My heart is fixed, O God, my heart is fixed; I will sing and give praise.

2 And do not be conformed to this world, but be transformed by the renewing of your mind, in order to prove by you what [is] that good and pleasing and perfect will of God.

8 This book of the law shall not depart out of your mouth, but you shall meditate on it by day and by night, so that you may be careful to do according to all that is written in it. For then you shall make your way prosperous, and then you shall act wisely.

10 With all my heart I have sought You; do not let me wander from Your commandments.11 I have hidden Your word in my heart, so that I might not sin against You.

5 And you shall love the LORD your God with all your heart and with all your soul and with all your might.6 And these words which I command you this day shall be in your heart.

46 And he said to them, Set your hearts to all the words which I testify among you today, which you shall command your sons to observe and to do, all the words of this law.

6 Do not be anxious about anything, but in everything by prayer and supplication, with thanksgiving, let your requests be made known to God.7 And the peace of God which passes all understanding shall keep your hearts and minds through Christ Jesus.

8 Draw near to God, and He will draw near to you. Cleanse [your] hands, sinners; and purify your hearts, double-minded ones.

8 You also be patient, establish your hearts, for the coming of your Lord draws near.

1 If then you were raised with Christ, seek those things which are above, where Christ is sitting at [the] right hand of God.
