The wise in heart [are willing to learn so they] will accept and obey commands (instruction),
But the babbling fool [who is arrogant and thinks himself wise] will come to ruin.

He who learns from instruction and correction is on the [right] path of life [and for others his example is a path toward wisdom and blessing],
But he who ignores and refuses correction goes off course [and for others his example is a path toward sin and ruin].
