1 Kings 5:12

10So Hiram gave Solomon cedar timber and cypress timber according to all his desire.

11Solomon gave Hiram twenty thousand cors of wheat for food to his household, and twenty cors of pure oil. Solomon gave this to Hiram year by year.

12The LORD gave Solomon wisdom, as he promised him. There was peace between Hiram and Solomon, and the two of them made a treaty together.

13King Solomon raised a levy out of all Israel; and the levy was thirty thousand men.

14He sent them to Lebanon, ten thousand a month by courses: for a month they were in Lebanon, and two months at home; and Adoniram was over the men subject to forced labor.
