Charles Ellicott Commentary 1 Kings 10:21

"And all king Solomon`s drinking vessels were of gold, and all the vessels of the house of the forest of Lebanon were of pure gold: none were of silver; it was nothing accounted of in the days of Solomon." — 1 Kings 10:21 (ASV)

None were of silver ... —See 2 Chronicles 9:27, “The king made silver in Jerusalem as stones.” The importation of silver (see 1 Kings 10:22) was by the navy of Tarshish; and the mention of the plentifulness of silver seems the reason for noticing the existence of this navy.
