2 Kings 9:22 is a place which mentions the name Jehu.  This is not the same Jehu that is listed as the son of Omri on the Black obelisk of Shalmaneser, where Israelites are depicted carrying gifts to a certain King Jehu.  This obelisk has an engraved image which is presumably a "sun" by one of the figures which I have pretty much reproduced in this pattern.
