Boyd’s Bible Dictionary:
(car). A two-wheeled vehicle, used for travel and war (Gen. 41:43; 46:29; 1 Kings 18:44; 2 Kings 5:9). In use by enemies of Israel (Josh. 11:4; Judg. 4:3; 1 Sam. 13:5). Adopted for war by David and Solomon (2 Sam. 8:4; 1 Kings 9:19; 10:26; 22:34; 2 Kings 9:16; Isa. 31:1).
Concise Bible Dictionary:
Except in Song of Sol. 3:9, where the word is appiryon and signifies “sedan, portable couch,” the chariots were vehicles with two wheels, used either for traveling or for war: they are often seen portrayed on Egyptian and Assyrian monuments (Gen. 41:43; Gen. 50:9; 1 Kings 4:26; Ezek. 23:24; Acts 8:28; Rev. 9:9). In Revelation 18:13 the word is ῥέδα, and some describe it as a vehicle with four wheels. The CHARIOT MAN in 2 Chronicles 18:33 is the driver, as in 1 Kings 22:34. A CHARIOT OF FIRE and horses of fire appeared when Elijah was carried up into heaven (2 Kings 2:11-12). When the king of Syria sought to take Elisha at Dothan he was protected by invisible chariots of fire (2 Kings 6:17).
