10644. 'And tear down their groves' means that their teachings are to be totally rejected. This is clear from the meaning of 'groves' as the teachings of the Church, at this point the teachings of the type of religion that is practised by idolaters, which are teachings that consist of falsity arising from evil. The reason why teachings are meant by 'groves' is that instances of perception or awareness of what is good and true are meant by 'trees', of perception among those who are in the Lord's celestial kingdom, and of awareness among those who are in His spiritual kingdom; and each species of a tree means a specific kind of perception or awareness. This accounts for the meaning of 'paradise gardens' and other 'gardens' as heavenly intelligence and wisdom, and for that of 'forests' as the knowledge which the natural man possesses. From all this it may be recognized why it is that teachings are meant by 'groves', and why it was that the ancients performed holy acts of worship in groves. For the Church among the ancients was a representative one, all of whose outward forms represented inner realities, such as they are in heaven, which have regard to the Lord, to love for Him and faith in Him, and to such things as are aspects of love and faith. The reason why groves, and also forests, gardens, and paradise gardens, as well as trees according to their species, mean such things lies in representative objects in the next life. The angels' intelligence and wisdom determine what kinds of objects appear there; for whatever makes its appearance has a celestial or spiritual origin.
