'Searches' in the Bible

and He who searches the hearts knows what the mind of the Spirit is, because He intercedes for the saints according to the will of God.

For to us God revealed them through the Spirit; for the Spirit searches all things, even the depths of God.

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