Another interpretation (of Prov. 28:20): A FAITHFUL PERSON WILL RECEIVE MANY BLESSINGS. This was Moses. Because of all the things that were done, he was remembered for himself; and they were blessed through him. Why? Because he was faithful. (Ibid., cont.:) BUT ONE WHO HASTENS TO BECOME RICH. This was Korah, who was a Levite and wanted to obtain the high priesthood as well.

Another interpretation (of Prov. 28:20): A FAITHFUL PERSON WILL RECEIVE MANY BLESSINGS. This was Moses, who became sole treasurer; and although he alone was treasurer, he summoned others and rendered an accounting through them.
