Once the main structure of the Temple was fully built, a new need arose. The heavy construction was complete after seven years of labor [מלבי״ם], but the space now required an expert artisan to craft its complex copper vessels and detailed decorations. To fulfill this task, Solomon sought out a dedicated professional.
There is a general consensus among commentators that the craftsman brought in for this work was not the King of Tyre, who had previously been in contact with Solomon. Instead, he was a highly skilled artisan who simply shared the king's name and lived in the same city. Solomon specifically chose this man because of his deep and unique expertise in working with copper. This mastery of the trade was a family legacy, a skill he had acquired and inherited directly from his father, who was also a professional copper craftsman [רלב״ג].
