JAAR . A Heb. name for a wood, forest, thicket, occurring about fifty times in the OT. It occurs once as a proper name, namely in Psalms 132:6 , where, speaking of the ark, the Psalmist says that it was heard of at Ephrathah and found at Jaar. The parallelism of Hebrew poetry requires that Jaar shall be regarded here as set over against Ephrathah. The ark was brought from the region of Bethlehem (Ephrathah), yea, from the woody heights of Kiriath-jearim.
