'Searches' in the Bible

He who searches the hearts knows what is on the Spirit's mind, because he makes intercession for the saints according to God.

But to us, God revealed them through the Spirit. For the Spirit searches all things, yes, the deep things of God.

I will kill her children with Death, and all the assemblies will know that I am he who searches the minds and hearts. I will give to each one of you according to your deeds.
