Jaar
JAAR (jā'ar, Heb. ya‘ăr, wood, forest). KJV and ASV of Ps.132.6 render the Hebrew word “the field of the wood,” whereas NIV and RSV render it as a place-name, “Jaar.” If it is a place, it can possibly be identified with Kiriath Jearim, where the ark was stored for twenty years before David brought it to Jerusalem.
