'Kindness' in the Bible

Let there be none to extend kindness unto him, neither let there be any to favour his fatherless children;

Because he remembered not to shew kindness, but persecuted the afflicted and needy man, and the broken in heart, to slay him.

Let the righteous smite me, it is kindness; and let him reprove me, it is an excellent oil which my head shall not refuse: for yet my prayer also is for them in their calamities.
