Easton's Bible Dictionary (1897)
And pl. Asherim in Revised Version, instead of “grove” and “groves” of the Authorized Version. This was the name of a sensual Canaanitish goddess Astarte, the feminine of the Assyrian Ishtar. Its symbol was the stem of a tree deprived of its boughs, and rudely shaped into an image, and planted in the ground. Such religious symbols (“groves”) are frequently alluded to in Scripture (Ex. 34:13; Judg. 6:25; 2 Kings 23:6; 1 Kings 16:33,
etc.). These images were also sometimes made of silver or of carved stone (2 Kings 21:7; “the graven image of Asherah,” R.V.). (See GROVE [1].).
Smith's Bible Dictionary (1863)
(straight), the name of a Phoenician goddess, or rather of the idol itself (Authorized Version “grove”). Asherah is closely connected with Ashtoreth and her worship, (Judges 3:7) comp. Judg 2:3; 6:25; 1Kin 18:19 Ashtoreth being, perhaps, the proper name of the goddess, whilst Asherah is the name of her image or symbol, which was of wood. See (Judges 6:25-30; 2 Kings 23:14)
