מלכים א ז:יד פירוש: רש״י

A coppersmith. A craftsman.¹⁸I.e., an expert in his trade, in the works of copper. The Chirom mentioned here is not King Chirom mentioned earlier [above 5:15].

He was filled with the wisdom and understanding and the knowledge [skill]. The three tools¹⁹These three qualities, wisdom, understanding and skill are the same three qualities that Betzalel, the builder of the Mishkon, possessed. See Shemos 31:3. with which the universe was created, as it is stated, “By wisdom He founded the earth, by understanding He established the heavens, by His knowledge the depths were broken up.”²⁰Mishlei 3:19— 20. The Beis [Hamikdosh] was built with these three.
