How about the eponymous Sappurisa Sutta (AN 4.73):


  "Now, a person endowed with these four qualities can be known as 'a
  person of integrity.' Which four?
  
  "There is the case where a person of integrity, when asked, does not
  reveal another person's bad points, to say nothing of when unasked.
  Furthermore, when asked, when pressed with questions, he is one who
  speaks of another person's bad points not in full, not in detail, with
  omissions, holding back. Of this person you may know, 'This venerable
  one is a person of integrity.'
  
  "Then again, a person of integrity, when unasked, reveals another
  person's good points, to say nothing of when asked. Furthermore, when
  asked, when pressed with questions, he is one who speaks of another
  person's good points in full &amp; in detail, without omissions, without
  holding back. Of this person you may know, 'This venerable one is a
  person of integrity.'
  
  "Then again, a person of integrity, when unasked, reveals his own bad
  points, to say nothing of when asked. Furthermore, when asked, when
  pressed with questions, he is one who speaks of his own bad points in
  full &amp; in detail, without omissions, without holding back. Of this
  person you may know, 'This venerable one is a person of integrity.'
  
  "Then again, a person of integrity, when asked, does not reveal his
  own good points, to say nothing of when unasked. Furthermore, when
  asked, when pressed with questions, he is one who speaks of his own
  good points not in full, not in detail, with omissions, holding back.
  Of this person you may know, 'This venerable one is a person of
  integrity.'
  
  "Monks, a person endowed with these four qualities can be known as 'a
  person of integrity.'"


And also the eponymous Sappurisa Sutta (MN 113):


  "But a person of integrity notices, 'It's not through having a
  high-ranking family that the quality of greed goes to its end; it's
  not through having a high-ranking family that the quality of
  aversion... the quality of delusion goes to its end. Even though one
  has not gone forth from a high-ranking family, if — practicing the
  Dhamma in line with the Dhamma, practicing masterfully — he is one who
  follows the Dhamma, he is to be honored for that, praised for that.'
  So, giving priority just to the practice, he neither exalts himself
  for having a high-ranking family nor disparages others. This is the
  quality of a person of integrity.
  
  "But a person of integrity notices, 'It's not through having a family
  of extensive wealth that the quality of greed goes to its end; it's
  not through having a family of extensive wealth that the quality of
  aversion... the quality of delusion goes to its end. Even though one
  has not gone forth from a family of extensive wealth, if — practicing
  the Dhamma in line with the Dhamma, practicing masterfully — he is one
  who follows the Dhamma, he is to be honored for that, praised for
  that.' So, giving priority just to the practice, he neither exalts
  himself for having a family of extensive wealth nor disparages others.
  This is the quality of a person of integrity.
  
  "But a person of integrity notices, 'It's not through being well-known
  &amp; highly regarded that the quality of greed goes to its end; it's not
  through being well-known &amp; highly regarded that the quality of
  aversion... the quality of delusion goes to its end. Even though one
  is not well-known &amp; highly regarded, if — practicing the Dhamma in
  line with the Dhamma, practicing masterfully — he is one who follows
  the Dhamma, he is to be honored for that, praised for that.' So,
  giving priority just to the practice, he neither exalts himself for
  being well-known nor disparages others. This is the quality of a
  person of integrity.
  
  "But a person of integrity notices, 'It's not through gains that the
  quality of greed goes to its end; it's not through gains that the
  quality of aversion... the quality of delusion goes to its end. Even
  though one is not one who gains robe-cloth, alms-food, lodgings, &amp;
  medicinal requisites for the sick, if — practicing the Dhamma in line
  with the Dhamma, practicing masterfully — he is one who follows the
  Dhamma, he is to be honored for that, praised for that.' So, giving
  priority just to the practice, he neither exalts himself for his gains
  nor disparages others. This is the quality of a person of integrity.
  
  "But a person of integrity notices, 'It's not through being a
  Dhamma-speaker that the quality of greed goes to its end; it's not
  through being a Dhamma-speaker that the quality of aversion... the
  quality of delusion goes to its end. Even though one is not a
  Dhamma-speaker, if — practicing the Dhamma in line with the Dhamma,
  practicing masterfully — he is one who follows the Dhamma, he is to be
  honored for that, praised for that.' So, giving priority just to the
  practice, he neither exalts himself for being a Dhamma-speaker nor
  disparages others. This is the quality of a person of integrity.
  
  "But a person of integrity notices, 'It's not through being a
  wilderness dweller that the quality of greed goes to its end; it's not
  through being a wilderness dweller that the quality of aversion... the
  quality of delusion goes to its end. Even though one is not a
  wilderness dweller, if — practicing the Dhamma in line with the
  Dhamma, practicing masterfully — he is one who follows the Dhamma, he
  is to be honored for that, praised for that.' So, giving priority just
  to the practice, he neither exalts himself for being a wilderness
  dweller nor disparages others. This is the quality of a person of
  integrity.
  
  "But a person of integrity notices, 'It's not through being one who
  eats only one meal a day that the quality of greed goes to its end;
  it's not through being one who eats only one meal a day that the
  quality of aversion... the quality of delusion goes to its end. Even
  though one is not one who eats only one meal a day, if — practicing
  the Dhamma in line with the Dhamma, practicing masterfully — he is one
  who follows the Dhamma, he is to be honored for that, praised for
  that.' So, giving priority just to the practice, he neither exalts
  himself for being one who eats only one meal a day nor disparages
  others. This is the quality of a person of integrity.
  
  "But a person of integrity notices, 'The Blessed One has spoken of
  non-fashioning even with regard to the attainment of the first jhāna,
  for by whatever means they construe it, it becomes otherwise from
  that.'  So, giving priority to non-fashioning, he neither exalts
  himself for the attainment of the first jhāna nor disparages others.
  This is the quality of a person of integrity.
  
  "A person of integrity notices, 'The Blessed One has spoken of
  non-fashioning even with regard to the attainment of the dimension of
  neither perception nor non-perception, for by whatever means they
  construe it, it becomes otherwise from that.' So, giving priority to
  non-fashioning, he neither exalts himself for the attainment of the
  dimension of neither perception nor non-perception nor disparages
  others. This is the quality of a person of integrity.
  
  "A person of integrity, completely transcending the dimension of
  neither perception nor non-perception, enters &amp; remains in the
  cessation of feeling &amp; perception. When he sees with discernment, his
  effluents are ended. This is a monk who does not construe anything,
  does not construe anywhere, does not construe in any way."
