🔼The name Maharai in the Bible
There's only one man named Maharai in the Bible. Maharai the Netophathite was one of David's mighty-men (2 Samuel 23:28, 1 Chronicles 11:30). This Maharai became one of the twelve commanders of Israel's army. His division consisted of Zerahites (1 Chronicles 27:13).
🔼Etymology of the name Maharai
The name Maharai may come from either of the verbs מהר but probably from מהר I (mahar I), meaning to hasten or be quick:
The letter י (yod) upon which our name ends, may either create an adjective (hastily), a possessive form (my haste), or may be a remnant of יה (Yah), which is short for יהוה, which is the name YHWH, or Yahweh.
For a meaning of the name Maharai, NOBSE Study Bible Name List thinks that the final yod marks an adjective and reads Swift, Hasty.
Jones' Dictionary of Old Testament Proper Names, on the other hand, mentions the Punic name Meherbal, which obviously contains the name Baal, and concludes the final yod of the name Maharai is a remnant of YHWH. hence Jones translates Maharai with Impetuosity Of The Lord.
BDB Theological Dictionary does not translate our name but does list it under the verb מהר I (mahar I), meaning to hasten or be quick.
