'Arts' in the Bible

And the Philistines sent for the priests and those who were wise in secret arts, and said to them, What are we to do with the ark of the Lord? How are we to send it away to its place?

For to go against his orders is like the sin of those who make use of secret arts, and pride is like giving worship to images. Because you have put away from you the word of the Lord, he has put you from your place as king.

Now Samuel was dead, and all Israel, after weeping for him, had put his body in its last resting-place in Ramah, his town. And Saul had put away from the land all those who had control of spirits and who made use of secret arts.

And the woman said to him, But you have knowledge of what Saul has done, how he has put away out of the land those who have control of spirits and the users of secret arts: why would you, by a trick, put me in danger of death?
