An asherah pole is like a tall stick in the ground that people used a long time ago to worship their gods. Sometimes, they would put decorations or carvings on the stick to make it look even prettier.
These poles were named after the goddess Asherah, who some people believed was their god. They would pray and sing songs around the pole to show their dedication to Asherah.
The idea of the asherah pole is similar to how some people today put up statues or symbols in their homes or make offerings to show their respect for their religion or belief system.
