these men

This refers to the men sent to King Hezekiah with a message and gifts from Berodach Baladan.

They have seen everything in my house. There is nothing among my valuable things that I have not shown them

Hezekiah repeats the same idea in two ways to emphasize his point. (See: rc://en/ta/man/translate/figs-hyperbole and rc://en/ta/man/translate/figs-parallelism)
