🔼The name Ishma in the Bible
The name Ishma (or Jishma, as some translations have it) occurs only once in the Bible. He is mentioned in the Chronicler's genealogy of Judah, in relation to Elam, and Jezreel, Idbash and Hazelelponi, but it's not clear how this relationship works (1 Chronicles 4:3).
🔼Etymology of the name Ishma
The name Ishma probably comes from the verb ישם (yasham), meaning to be desolate:
It's not clear how the letter א (aleph) got involved in this name but it may be due to a fancy Aramaic twist that someone figured this name needed.
For a meaning of the name Ishma, NOBSE Study Bible Name List reads Desolate and Jones' Dictionary of Old Testament Proper Names has Desolateness. BDB Theological Dictionary does not interpret our name but does list it under the verb ישם (yasham).
