'Simple minded' in the Bible

To make the simple-minded sharp, and to give the young man knowledge, and serious purpose:

“How long, O naive ones, will you love being simple-minded?And scoffers delight themselves in scoffingAnd fools hate knowledge?

“Leave [behind] your foolishness [and the foolish] and live,And walk in the way of insight and understanding.”

You shall do this on the seventh [day] of the month for everyone who goes astray [and sins through error or ignorance] and for him who is naive; so shall you make atonement for the temple (house).

At that time Jesus spoke and said, "I praise thee, Father, Lord of heaven and earth, for hiding all this from the wise and learned and revealing it to the simpleminded;

He thrilled with joy at that hour in the holy Spirit, saying, "I praise thee, Father, Lord of heaven and earth, for concealing this from the wise and learned and revealing it to the simple-minded; yes, Father, I praise thee that such was thy chosen purpose." Then turning to the disciples he said,

For such people do not serve our Lord Christ, but their own appetites and base desires. By smooth and flattering speech they deceive the hearts of the unsuspecting [the innocent and the naive].

Your fidelity to the truth is everywhere known. I rejoice over you, therefore, but I wish you to be wise as to what is good, and simple-minded as to what is evil.
