The Meaning of Kol Ish in the Construction of the Mishkan

35:21 “ויבאו כל איש אשר נשאו לבו, וכל אשר נדבה רוחו אתו הביאו את תרומת ד' למלאכת אהל מועד ולכל עבודתו ולבגדי הקודש”

“Every man whose heart inspired him came; and everyone who is generous of spirit moved him – brought the portion of Hashem for the work of the Ohel Moed, for all its labor and for the garments of the holy.” The word, “כל” refers to at least two. How does the Posuk say, “כל איש” – when the כל implies at least two, and איש is one? The following Divrei Torah will expound on this topic, and perhaps support the P’shat offered in the closing paragraph.
