Worshiping Idols

Worship idols is to:

To worship God with a molten image

Exodus 32:4-6

4 He took what they handed him and made it into an idol cast in the shape of a calf, fashioning it with a tool. Then they said, “These are your gods, O Israel, who brought you up out of Egypt.”

5 When Aaron saw this, he built an altar in front of the calf and announced, “Tomorrow there will be a festival to the LORD.”

6 So the next day the people rose early and sacrificed burnt offerings and presented fellowship offerings. Afterward they sat down to eat and drink and got up to indulge in revelry.

Psalms 106:19-20

19 At Horeb they made a calf and worshiped an idol cast from metal.

20 They exchanged their Glory for an image of a bull, which eats grass.

Worship angels

Colossians 2:18

Do not let anyone who delights in false humility and the worship of angels disqualify you for the prize. Such a person goes into great detail about what he has seen, and his unspiritual mind puffs him up with idle notions.

Worship the sun moon and stars

Deuteronomy 4:19

And when you look up to the sky and see the sun, the moon and the stars—all the heavenly array—do not be enticed into bowing down to them and worshiping things the LORD your God has apportioned to all the nations under heaven.

Deuteronomy 17:3

And contrary to my command has worshiped other gods, bowing down to them or to the sun or the moon or the stars of the sky,

Worship evil spirits

Revelation 9:20

The rest of mankind that were not killed by these plagues still did not repent of the work of their hands; they did not stop worshiping demons, and idols of gold, silver, bronze, stone and wood—idols that cannot see or hear or walk.
