They also built them high places; they followed the example of the Israelites, although they were better instructed, and had the temple in their kingdom, and liberty of access to it, which was denied to the Israelites; and the privilege of worshipping God in his own way, and the counsels, and sermons, and examples of the priests and Levites to and stablish them, and the dreadful example of Israel's horrid apostacy to caution and terrify them. The building of high places was unlawful, and now especially when the temple was built, and ready to receive them; unnecessary, and therefore expressed a greater contempt of God and his express command to the contrary. Images and groves; not only after the manner of the heathens and Israelites, but against a direct and particular prohibition. Under every green tree: the people were universally corrupted; which is a prodigious sin, all things considered, and is a clear evidence of the greatness and depth of the original corruption of man's nature, which without God's grace is ready to break forth into all sorts of wickedness.
