Deuteronomy 16:21

Verse 21. Tree. The pagans had consecrated different sorts of trees to their idols. They always planted groves near their temples, to increase the reverential awe, and but too often to hide the abominations which were there committed. The Hebrews frequently imitated them in these particulars. Yet Hecateus observes, that no tree was to be seen near the temple of Jerusalem.
