'Minds' in the Bible

Now some of the experts in the law were sitting there, turning these things over in their minds:

At once perceiving by His spirit that they were reasoning within themselves, Jesus asked them, "Why do you thus argue in your minds?

So they went out and preached that men should repent [that is, think differently, recognize sin, turn away from it, and live changed lives].

For they had not learned the lesson taught by the loaves, but their minds were dull.

He perceived what they were saying, and He said to them, "What is this discussion of yours about having no bread? Do you not yet see and understand? Are your minds so dull of comprehension?
