2 Kings 16:4

“You shall utterly destroy all the places where the nations whom you shall dispossess serve their gods, on the high mountains and on the hills and under every green tree.

Only the high places were not taken away; the people still sacrificed and burned incense on the high places.

Ahaz was twenty years old when he became king, and he reigned sixteen years in Jerusalem; and he did not do what was right in the sight of Yahweh, as David his father had done.

For they provoked Him with their high places And aroused His jealousy with their graven images.

The vision of Isaiah the son of Amoz concerning Judah and Jerusalem, which he beheld in the days of Uzziah, Jotham, Ahaz, and Hezekiah, kings of Judah.

Who inflame yourselves among the oaks, Under every green tree, Who slaughter the children in the ravines, Under the clefts of the cliffs?

“Then you will know that I am Yahweh when their slain are among their idols all around their altars, on every high hill, on all the tops of the mountains, under every green tree, and under every leafy oak—the places where they offered a soothing aroma to all their idols.

The word of Yahweh which came to Hosea the son of Beeri, in the days of Uzziah, Jotham, Ahaz, and Hezekiah, kings of Judah, and in the days of Jeroboam the son of Joash, king of Israel.

The word of Yahweh which came to Micah of Moresheth in the days of Jotham, Ahaz, and Hezekiah, kings of Judah, which he beheld concerning Samaria and Jerusalem.
