1 Kings 5:10-12

So Hiram gave Solomon as much as he desired of the cedar and cypress timber. Solomon then gave Hiram 20,000 kors of wheat as food for his household, and twenty kors of beaten oil; thus Solomon would give Hiram year by year. 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.
