Amidah-Vayakhel-Holiness That Expands

Holiness has the effect of awakening holiness. It cultivates the better nature of those who observe it. We learned that when the artists who fashioned the holy objects for the Tabernacle reported a surplus of materials, Moses did not ordain that no more materials should be brought, but that no more work should be done (Exodus 36:4–6). This was because the people, aroused to a sense of holiness and dedication, could not be restrained from bringing gifts as long as a holy work was being performed. (Menorah haTehorah, page 71)
