Ba'ca. (weeping). The Valley of Baca. A valley in Palestine, through which the exiled Psalmist sees, in vision, the pilgrims passing in their march towards the sanctuary of Jehovah at Zion. Psalms 84:6. That it was a real locality is most probable from the use of the definite article before the name.
The rendering of the Targum is Gehenna, that is, the Ge-Hinnom or ravine below Mount Zion. This locality agrees well with the mention of balsam (Authorized Version, "mulberry") trees in 2 Samuel 5:23.
