1 Kings 5:7-11

And it came to pass, when Hiram heard the words of Solomon, that he rejoiced greatly, and said, Blessed be the LORD this day, which hath given unto David a wise son over this great people.

And Hiram sent to Solomon, saying, I have considered the things which thou sentest to me for: and I will do all thy desire concerning timber of cedar, and concerning timber of fir.

My servants shall bring them down from Lebanon unto the sea: and I will convey them by sea in floats unto the place that thou shalt appoint me, and will cause them to be discharged there, and thou shalt receive them: and thou shalt accomplish my desire, in giving food for my household.

So Hiram gave Solomon cedar trees and fir trees according to all his desire.

And Solomon gave Hiram twenty thousand measures of wheat for food to his household, and twenty measures of pure oil: thus gave Solomon to Hiram year by year.
