Judges 3:6-7

They took their daughters, and served their gods Were drawn to idolatry by the persuasions and examples of their yoke-fellows. And served Baalim and the groves Or, Baalim in groves; that is, false gods, or rather their images, set up under shady trees, contrary to the command given Exodus 34:13. Some expositors, however, think the meaning is, Baalim and Ashtaroth; for by the addition of a single letter, the Hebrew word rendered groves, will be Ashtaroth, and the greater part of the versions so render it, understanding thereby goddesses, as distinguished from Baalim or lords. It must be acknowledged, however, that the trees themselves, which composed those shady retreats in which they placed their idols, and which were consecrated to their honour, were accounted sacred by the ancient pagans, and held in great veneration. They decorated them with ribands and lights, made vows to them, and hung the spoils of their enemies upon them: insomuch that it was customary for travellers to stop, when they were to pass by them, and approach them with veneration and religious awe, as if they had been the habitation of some god.
