The high places of Baal, or "Bamoth-Baal." Perhaps the Bamoth mentioned in Numbers 21:19, Numbers 21:20. This is, however, by no means certain, because high places were no doubt numerous, and that Bamoth would seem to have been too far from the present camp of Israel. In any case they crossed the Arnon, and ran some risk by adventuring themselves on hostile territory. That thence he might see the utmost part of the people. According to the quasi-sacramental character attributed to the cursing of a seer, it was held necessary that the subject of the curse should be in view. Balak desired to attain this object with as little risk as possible, and therefore he took Balaam first of all to these heights, whence a distant and partial view of Israel might be had.
