Ibn Ezra on Exodus 35:32/אבן עזרא על שמות ל״ה:ל״ב

1AND TO DEVISE SKILFUL WORKS. Ve-la-chashov machashavot (and to devise skilful works) is to be interpreted as meaning: and to devise in his heart designs which were never seen. [IN GOLD, AND IN SILVER.] For some people are skilled in working with gold but not in working with silver. Others are skilled stone masons but are not skilled wood carvers. However, Bezalel was a master of all of these crafts.
