'Inmost' in the Bible

“They conceive mischief and bring forth wickedness,And their inmost soul prepares deceit and fraud.”

Behold, You desire truth in the innermost being,And in the hidden part [of my heart] You will make me know wisdom.

Let death come deceitfully upon them;Let them go down alive to Sheol (the nether world, the place of the dead),For evil [of every kind] is in their dwelling and in their hearts, in their midst.

For I joyfully delight in the law of God in my inner self [with my new nature],

“This is the covenant that I will make with themAfter those days, says the Lord:I will imprint My laws upon their heart,And on their mind I will inscribe them [producing an inward change],”He then says,

And I will kill her children (followers) with pestilence [thoroughly annihilating them], and all the churches will know [without any doubt] that I am He who searches the minds and hearts [the innermost thoughts, purposes]; and I will give to each one of you [a reward or punishment] according to your deeds.
