Hosea 4:13

"On the tops of the mountains, they sacrificed, and on the hills, they burned incense under an oak and a poplar and a terebinth because its shade was good." According to the Law, it is commanded that one should not offer sacrifice to the Lord anywhere other than the place that the Lord God chooses. Trees are not to be planted near the altar so that a passive and indulgent religion does not overthrow the austerity of the one true religion. On the contrary, Israel was sacrificing on the mountains and burning incense on the hills, loving the high places of the earth, for they had forsaken the Most High God and sought shadows, having lost the truth. This is what we read about each king: "But the high places were not taken away; the people still sacrificed and burned incense on the high places" (3 Kings 22:44), which in Hebrew is called Bama. Heretics promise themselves the sublimity of their doctrines and sacrifice under oak, poplar and terebinth, under barren trees, having neither fig nor vine, under which the Saint is said to rest. However, they sometimes assume a terebinth for themselves, which, according to Isaiah, has no leaves, so that they may seem to imitate the example of Abraham. (Isaiah VI)
