The Mishkan was built with זהב וכסף ונחושת, gold, silver, and copper. Generally, we view the pursuit of gold as a strictly material pursuit.
Our Parsha teaches that זהב can also symbolize a golden holy pursuit. Someone can have a golden personality. His word could be as good as gold. We even say that silence is golden.
Rabbeinu Bechaye suggests that the word זהב hints to the three Torah blessings of ברכת המזון.
The letter “ז” refers to the first blessing of הזן, that Hashem sustains us. The “ה” refers to הארץ where we praise Hashem for the good Land of Israel. And the “ב” refers to the third blessing of בונה ירושלים, that we ask that ירושלים be rebuilt,
The real זהב that we are to pursue is recognizing Hashem’s blessings and appreciating Israel and Jerusalem.
