Isaiah 1:29

For they shall be ashamed of the oaks which ye have desired, and ye shall be confounded for the gardens that ye have chosen.

They shall be ashamed (Romans 6:21) of the oaks. Others translate ( 'eeyliym (H352)) elms; or else the terebinth or turpentine trees. Groves were dedicated to idols. The Druids took their name from the Greek for oaks. A sacred tree is often found in Assyrian sculpture: the symbol of the starry hosts, tsaabaa' (H6635). Hence, the Septuagint, Syriac, and Arabic translate, 'the idols.'

Ye shall be confounded for the gardens - planted enclosures for idolatry; the awful counterpart of the garden of Eden.
