The name Lasha in the Bible
Etymology and meaning of the name Lasha
The etymology of the name Lasha is unknown so we're left to guess. Jones' Dictionary of Old Testament Proper Names traces this name back to an unused Hebrew root, and a parallel Arabic word meaning to pierce, and reads Fissure. For untraceable reasons, NOBSE Study Bible Name List reads Bursting Forth. BDB Theological Dictionary makes no attempt.
Perhaps this name is a construct: ל + שע.
The particle ל (le), means to or towards:
The segment שע may come from שעה (sha'a), meaning look at, regard, or שעע (sha'a'), meaning blinded, or שעע (sha'a') meaning sport, take delight in:
Whatever the original name giver meant to say with Lasha can no longer be determined, but it looks like To Be Viewed, To Be Blinded, or To Be Played With.
