Matthew 6:21

For where your treasure is, there will your heart be also.

While we look not at the things which are seen, but at the things which are not seen: for the things which are seen are temporal; but the things which are not seen are eternal.

Keep thy heart with all diligence; for out of it are the issues of life.

And wisdom and knowledge shall be the stability of thy times, and strength of salvation: the fear of the LORD is his treasure.

Take heed, brethren, lest there be in any of you an evil heart of unbelief, in departing from the living God.

O Jerusalem, wash thine heart from wickedness, that thou mayest be saved. How long shall thy vain thoughts lodge within thee?

O generation of vipers, how can ye, being evil, speak good things? for out of the abundance of the heart the mouth speaketh.

Thou hast neither part nor lot in this matter: for thy heart is not right in the sight of God.

But thine eyes and thine heart are not but for thy covetousness, and for to shed innocent blood, and for oppression, and for violence, to do it.

Grace to you, and peace, from God our Father and the Lord Jesus Christ.

I Paul have written it with mine own hand, I will repay it: albeit I do not say to thee how thou owest unto me even thine own self besides.
