1 Samuel 13:19
And no blacksmith could be found in all the land of Israel, because the Philistines had said, “The Hebrews must not be allowed to make swords or spears.”
2 Chronicles 2:7, 14
Send me, therefore, a craftsman skilled in engraving to work with gold and silver, with bronze and iron, and with purple, crimson, and blue yarn. He will work with my craftsmen in Judah and Jerusalem, whom my father David provided. / He is the son of a woman from the daughters of Dan, and his father is a man of Tyre. He is skilled in work with gold and silver, bronze and iron, stone and wood, purple, blue, and crimson yarn, and fine linen. He is experienced in every kind of engraving and can execute any design that is given him. He will work with your craftsmen and with those of my lord, your father David.
