אור החיים - 36:8 “ויעשו כל חכם לב בעשי המלאכה את המשכן עשר יריעת שש משזר ותכלת וארגמן ותולעת שני, כרובים מעשה חשב אתם” – “The wise-hearted among those doing the work made the Mishkan ten panels of twisted linen, and turquoise wool. And purple wool, and scarlet wool; they made them, the work of an artist – Keruvim.” Why does the Posuk here say, “ויעשו” –a Loshon Rabbim, plural, while after this, the Torah continually says, “ויעש” in Loshon Yachid? Was it numerous people who made the Mishkan or one person? There were many people involved in the construction of the Mishkan. Each and every person has his own way of doing work, generally speaking no two individuals produce the same exact work. However, by the construction of the Mishkan, a miracle occurred and it was as if one person constructed everything, so that everything was perfectly uniform.
