🔼The name Ahishar in the Bible
The only Ahishar in the Bible is king Solomon's chief of staff (1 Kings 4:6). Apart from this brief cameo, Ahishar has no further role in the Bible.
🔼Etymology of the name Ahishar
The name Ahishar consists of two elements. The first part comes from the word אח (ah), meaning brother:
The origin of the second part of the name Ahishar is not clear and scholars disagree.
BDB Theological Dictionary and NOBSE Study Bible Name List derive it from the verb שיר (shir), meaning to sing:
And indeed, our verb shir belongs to a group of verbs of which the letter yod drops out in certain grammatical constructions. Hence, for a meaning of the name Ahishar, both BDB and NOBSE read My Brother Has Sung.
Alfred Jones (Dictionary of Old Testament Proper Names), however, sees more in the verb שרר (shrr), which is unused in the Bible but which may have meant to be hard or firm:
Hence Jones reads Brother Of Firmness.
The renowned theologian Gesenius also has a different idea and proposes relations with the verb ישר (yashar) meaning to be upright or just:
Hence Gesenius reads Brother Of The Upright.
Depending on our leanings, the name Ahishar may mean My Brother Has Sung, or Brother Of Singing. It may mean Brother Of Firmness or My Brother Is Firm, or it may mean My Brother Is Upright, or Brother Of Uprightness.
And of course, for every "Brother" a reader may impose "Friend" or "Ally".
