During Israel’s journey through the wilderness, two groups combined to rebel against the leadership of Moses and Aaron. One was a group of 250 prominent Levites under the leadership of Korah who were envious that only Aaron and his family were allowed to be priests. The other group was headed by two from the tribe of Reuben who were envious of Moses’ position as national leader (Num 16:1-3). In a public demonstration of whom he had chosen to be his priests, God put Korah to the test.
He challenged Korah and his fellow Levite rebels to burn incense, something that normally only Aaron and his sons were allowed to do (Num 16:5-19). Korah and the two Reubenites were separated from the 250 Levites for the test. The outcome was that the three leaders were swallowed up by the earth, and the 250 Levites were burnt to death by fire from God (Num 16:32,35; Jude 11). Centuries later, descendants of Korah restored some respectability to the family name when they became gatekeepers, singers and musicians in the temple (1 Chron 6:31-38; 15:17,19; 16:41-42; 26:19). They collected or wrote a number of psalms that have been preserved in the Bible (Ps 42; 44-49; 84-85; 87-88).
