🔼The name Korah in the Bible
There are four men named Korah in the Bible, but most famous is Korah, son of Izhar, and the cousin of Moses and Aaron, who claimed that since he too was a great-grandson of Levi he too should be allowed to draft Law, and got himself descended live into Sheol (Numbers 16:1). In the Greek New Testament the name Korah appears only in the letter of Jude, who declares men who revile things they do not understand to persist in the rebellion of Korah (Jude 1:11, spelled Κορε Kore).
The Levitical sub-class "sons of Korah" or "Korahites" (קרחי) are descendants of the famous cousin (Exodus 6:24). They were not executed along with their father (Numbers 26:11) and became gatekeepers (1 Chronicles 26:19), soldiers (1 Chronicles 12:6), and musicians (having written an untold number of Psalms, eleven of which are extant and Canonized — see Psalm 42 to Psalm 88).
Besides the famous Korah, there are three more Korahs mentioned in the Bible:
🔼Etymology and meaning of the name Korah
The name Korah comes from the root group קרח (qerah):
The name Korah is identical to the word קרח (qerah), meaning frost. Hence Jones' Dictionary of Old Testament Proper Names translates this name with Ice or Hail.
NOBSE Study Bible Name List and BDB Theological Dictionary, however, derive Korah from the identical root קרח (qarah), to be bald. Hence NOBSE and BDB both read Baldness, although BDB adds a question mark.
