'Hearts Of Men' in the Bible

For from within, [that is] out the heart of men, come base and malevolent thoughts and schemes, acts of sexual immorality, thefts, murders, adulteries,

And He who searches the hearts knows what the mind of the Spirit is, because the Spirit intercedes [before God] on behalf of God’s people in accordance with God’s will.

And I will put her children to death; and all the churches will see that I am he who makes search into the secret thoughts and hearts of men: and I will give to every one of you the reward of your works.
