'Alone' in the Bible

[Confine yourself to your own wife.] Let your children be yours alone,And not the children of strangers with you.

If you are wise, you are wise for yourself [for your own benefit];If you scoff [thoughtlessly ridicule and disdain], you alone will pay the penalty.

A servant will not be corrected by words alone;For though he understands, he will not respond [nor pay attention].
