Another interpretation of (Proverbs 28:20): "A faithful man abounds with blessings." This was Moses. Concerning all the things that were made, he was mentioned over them, and they were blessed through his hands. Why? Because he was faithful. "But one who hastens to be rich" (ibid.)—this was Korah, who was a Levite and sought additionally to take hold of the high priesthood.
Moses the Faithful and Korah Who Grasped at the Priesthood
Midrash Tanchuma Buber, Pekudei 1:2
ד"א איש אמונות. זה היה משה על כל הדברים שנעשו נזכר עליהם, והיו מתברכות על ידיו, למה שהוא נאמן. ואץ להעשיר, זה קרח שהיה לוי וביקש עוד ליטול כהונה גדולה.
