'Builder's' in the Bible

So King Ahaz went to meet Tiglath-Pileser the king of Assyria [in] Damascus, and he saw the altar which [was] in Damascus, so King Ahaz sent to Uriah the priest the builder's plan of the altar and the {exact model of how it had been made}.

This is the builder's son, isn't it? His mother is named Mary, isn't she? His brothers are James, Joseph, Simon, and Judas, aren't they?

each builder's work will be plainly seen, for the Day will make it clear, because it will be revealed by fire. And the fire will test what kind of work each has done.
