Ze'ev Wolf of Zhitomir on Exodus 25:1-2 (Parasha Terumah), from Or Ha-Me'ir

Hebrew text and provisional English translation.

... And this is an important principle in the Torah and [in] worship of God, that in everything in the world there is a "hint of Wisdom" [Zohar, Vayechi 23:183; Zohar, Sh'lach 6:36} so that the wise man can stir up his heart inside him to the worship of his Creator, even in eating and drinking and in business dealings.

and their giving with the food, also there [in them] is an aspect of worship of the Creator, blessed be He.

"...and nothing is reduced from your work..." [Exodus 5:11], and if it will become clear to us when it further pleases HaShem, the explanation is to think thoughts to make in gold and in silver, as if to say: even in the time when one is busy to make in gold and in silver, when going to "your work" for reason of bringing [home] one's maintainance [earnings], also then it is necessary to think holy thoughts, to cleave one's thought to the majesty of His Blessed Divinity, and to raise from there holy sparks and letters of the Torah...
