1 Kings 5:12-16

And the Lord gave wisdom to Solomon, just as He promised him; and there was peace between Hiram and Solomon, and the two of them made a covenant. Conscription of Laborers

Now King Solomon conscripted forced laborers from all Israel; and the forced laborers numbered thirty thousand men.

Then he sent them to Lebanon, ten thousand a month in shifts; they were in Lebanon for a month, and two months at home. And Adoniram was in charge of the forced laborers.

Now Solomon had seventy thousand porters, and eighty thousand stonemasons in the mountains,

besides Solomon’s 3,300 chief deputies who were in charge of the project and ruled over the people who were doing the work.
