'Searches' in the Bible

And the one who searches our hearts knows what the mindset of the Spirit [is], because he intercedes on behalf of the saints according to [the will of] God.

For to us God has revealed [them] through the Spirit. For the Spirit searches all [things], even the depths of God.

And I will kill her children with deadly disease, and all the churches will know that I am the one who searches minds and hearts, and I will give to each one of you according to your deeds.
