'Kindness' in the Bible

Let there be none to extend kindness unto him; Neither let there be any to have pity on his fatherless children.

Because he remembered not to show kindness, But persecuted the poor and needy man, And the broken in heart, to slay them .

Let the righteous smite me, it shall be a kindness; And let him reprove me, it shall be as oil upon the head; Let not my head refuse it: For even in their wickedness shall my prayer continue.
