'Cavalry' in the Bible

As Elisha continued to watch, he cried out, "My father! My father! The chariots of Israel and its cavalry!" Then he did not see Elijah anymore.

"I'm coming," Jehoshaphat replied. "I'm like you! My army will act like your army and my cavalry like your cavalry," Then Jehoshaphat added: "What road do we take?" Jehoram answered, "We'll go along the Edom desert road."

For the Aramean king had left only 50 cavalry, ten chariots, and 10,000 soldiers out of the army belonging to Jehoahaz, because the king of Aram had destroyed the others, making them like chaff left over after threshing.
