Here is one verse:
Ezekiel 8:16 King James Version (KJV)
16 And he brought me into the inner court of the Lord’s house, and, behold, at the door of the temple of the Lord, between the porch and the altar, were about five and twenty men, with their backs toward the temple of the Lord, and their faces toward the east; and they worshipped the sun toward the east.
Below is another verse about the worship of the sun:
Deuteronomy 4:19 King James Version (KJV)
19 And lest thou lift up thine eyes unto heaven, and when thou seest the sun, and the moon, and the stars, even all the host of heaven, shouldest be driven to worship them, and serve them, which the Lord thy God hath divided unto all nations under the whole heaven.
The Lord did not command the worship of the sun:
Deuteronomy 17:3 King James Version (KJV)
3 And hath gone and served other gods, and worshipped them, either the sun, or moon, or any of the host of heaven, which I have not commanded;
To worship the sun is denial of the God that is above:
Job 31:26-28 King James Version (KJV)
26 If I beheld the sun when it shined, or the moon walking in brightness;
27 And my heart hath been secretly enticed, or my mouth hath kissed my hand:
28 This also were an iniquity to be punished by the judge: for I should have denied the God that is above.
The “idolatrous priests” were” put down” for burning incense to the sun:
2 Kings 23:5 King James Version (KJV)
5 And he put down the idolatrous priests, whom the kings of Judah had ordained to burn incense in the high places in the cities of Judah, and in the places round about Jerusalem; them also that burned incense unto Baal, to the sun, and to the moon, and to the planets, and to all the host of heaven.
The bones of those who worshipped the sun, “shall not be gathered, nor be buried” but will be “dung upon the face of the earth”:
Jeremiah 8:1-2 King James Version (KJV)
1 At that time, saith the Lord, they shall bring out the bones of the kings of Judah, and the bones of his princes, and the bones of the priests, and the bones of the prophets, and the bones of the inhabitants of Jerusalem, out of their graves:
2 And they shall spread them before the sun, and the moon, and all the host of heaven, whom they have loved, and whom they have served, and after whom they have walked, and whom they have sought, and whom they have worshipped: they shall not be gathered, nor be buried; they shall be for dung upon the face of the earth.
