While the lexical entry describes cedar trees and cedar-wood products extensively, the single New Testament occurrence uses this as a place name: the Kidron valley between Jerusalem and the Mount of Olives. John 18:1 marks this as the location Jesus crossed before his arrest in Gethsemane. The transliterations across languages (Kedron, Kédrōn, Cédron, Kidron) preserve the Hebrew name, though its etymology may relate either to cedars or to darkness/turbidity.
