'Simple' in the Bible

That prudence (good judgment, astute common sense) may be given to the naive or inexperienced [who are easily misled],And knowledge and discretion (intelligent discernment) to the youth,

“How long, O naive ones [you who are easily misled], will you love being simple-minded and undiscerning?How long will scoffers [who ridicule and deride] delight in scoffing,How long will fools [who obstinately mock truth] hate knowledge?

“For the turning away of the naive will kill them,And the careless ease of [self-righteous] fools will destroy them.

And among the naive [the inexperienced and gullible],I saw among the youthsA young man lacking [good] sense,

“O you naive or inexperienced [who are easily misled], understand prudence and seek astute common sense;And, O you [closed-minded, self-confident] fools, understand wisdom [seek the insight and self-discipline that leads to godly living].

“Whoever is naive or inexperienced, let him turn in here!”As for him who lacks understanding, she says,

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

The foolish woman is restless and noisy;She is naive and easily misled and thoughtless, and knows nothing at all [of eternal value].

“Whoever is naive or inexperienced, let him turn in here!”And to him who lacks understanding (common sense), she says,

The naive [are unsophisticated and easy to exploit and] inherit foolishness,But the sensible [are thoughtful and far-sighted and] are crowned with knowledge.

Strike a scoffer [for refusing to learn], and the naive may [be warned and] become prudent;Reprimand one who has understanding and a teachable spirit, and he will gain knowledge and insight.

A prudent and far-sighted person sees the evil [of sin] and hides himself [from it],But the naive continue on and are punished [by suffering the consequences of sin].

A prudent man sees evil and hides himself and avoids it,But the naive [who are easily misled] continue on and are punished [by suffering the consequences of sin].
