There have been a few modern teachers who have taught this sutta… such as Ven. U. Dhammajiva Maha Thero (18 dhamma lectures) or Ajahn Appichato (1 BSWA talk) or Ayya Vayama.
Are you perhaps looking for the ancient commentaries on this sutta? Those are hard to find in English- check here… maybe Ven @sujato can guide us?
