Deuteronomy 16:21
Thou shalt not plant thee a grove of any trees near unto the altar of the LORD thy God, which thou shalt make thee.
Thou shall not plant thee a grove of any trees,.... Of any sort of trees, as oaks or any other; not but that it was lawful to plant trees and groves of them, but not for a religious or idolatrous use: particularly
near unto the altar of the LORD thy God, which thou shalt make thee; as the Heathens did near their altars, lest it should be thought to be done for a like superstitious and idolatrous use; which evil the Jews sometimes fell into in the times of wicked reigns, and which their good and pious kings removed and destroyed; see 2 Kings 18:4 and Hecataeus {b}, an Heathen historian, relates of the city of Jerusalem, that there were there no image, nor plantation, nor grove, nor any such thing.
