Deuteronomy 12:2 Ye shall utterly destroy all the places, wherein the nations which ye shall possess served their gods, upon the high mountains, and upon the hills, and under every green tree:
Ahaz reigned in Jerusalem and he put Idols everywhere:
1 Kings 14:23 For they also built them high places, and images, and groves, on every high hill, and under every green tree.
2 Kings 16:4 And he sacrificed and burnt incense in the high places, and on the hills, and under every green tree.
2 Kings 17:10 And they set them up images and groves in every high hill, and under every green tree:
2 Chronicles 28:4 He sacrificed also and burnt incense in the high places, and on the hills, and under every green tree.
Warning from The Lord:
Isaiah 57:5 Enflaming yourselves with idols under every green tree, slaying the children in the valleys under the clifts of the rocks?
The Lord knows of Israel’s sin:
Jeremiah 2:20 For of old time I have broken thy yoke, and burst thy bands; and thou saidst, I will not transgress; when upon every high hill and under every green tree thou wanderest, playing the harlot.
Jeremiah 3:6 The LORD said also unto me in the days of Josiah the king, Hast thou seen that which backsliding Israel hath done? she is gone up upon every high mountain and under every green tree, and there hath played the harlot.
Jeremiah 3:13 Only acknowledge thine iniquity, that thou hast transgressed against the LORD thy God, and hast scattered thy ways to the strangers under every green tree, and ye have not obeyed my voice, saith the LORD.
Because of Israel’s sin:
Ezekiel 6:13 Then shall ye know that I am the LORD, when their slain men shall be among their idols round about their altars, upon every high hill, in all the tops of the mountains, and under every green tree, and under every thick oak, the place where they did offer sweet savour to all their idols.
Ezekiel 17:24 And all the trees of the field shall know that I the LORD have brought down the high tree, have exalted the low tree, have dried up the green tree, and have made the dry tree to flourish: I the LORD have spoken and have done it.
Ezekiel 20:47 And say to the forest of the south, Hear the word of the LORD; Thus saith the Lord GOD; Behold, I will kindle a fire in thee, and it shall devour every green tree in thee, and every dry tree: the flaming flame shall not be quenched, and all faces from the south to the north shall be burned therein.
The Green Tree usually represents good times:
A warning from the Lord Jesus:
Luke 23:31 For if they do these things in a green tree, what shall be done in the dry?
