'Horsemen' in the Bible

Then Adonijah the son of [David’s wife] Haggith exalted himself, saying, “I [the eldest living son] will be king.” So [following Absalom’s example] he prepared for himself chariots and horsemen, and fifty men to run before him.

Solomon also had 40,000 stalls of horses for his chariots, and 12,000 horsemen.

and all the storage cities [for surplus provisions] which Solomon had, and the cities for his chariots and cities for his horsemen, and whatever it pleased Solomon to build in Jerusalem, in Lebanon, and in all the land under his rule.

But Solomon did not make slaves of the sons of Israel; for they were men of war (soldiers), his servants, his officers, his captains, his chariot commanders, and his horsemen.

Now Solomon collected chariots and horsemen; he had 1,400 chariots and 12,000 horsemen, which he stationed in the chariot cities and with the king in Jerusalem.

And each one killed his man; and the Arameans (Syrians) fled and Israel pursued them. Ben-hadad king of Aram escaped on a horse with horsemen.
