Boyd’s Bible Dictionary:
(smiter). An artificer in iron, brass, or other metals (Gen. 4:22; 1 Sam. 13:19-22).
Concise Bible Dictionary:
The well-known worker in metal. When the Philistines were oppressing Israel we read “there was no smith found throughout all the land of Israel: for the Philistines said, Lest the Hebrews make them swords or spears.” Thus the people of God were unarmed before their enemies. They had to resort to the Philistines even to sharpen their agricultural tools (1 Sam. 13:19-20). This was different afterward, for when the people were carried into captivity, smiths are named among the captives (2 Kings 24:14, 16).
