'Forbidden' in the Bible

‘When a ruler or leader sins and unintentionally does any one of the things the Lord his God has commanded not to be done, and he becomes guilty,

And if a soul sin, and commit any of these things which are forbidden to be done by the commandments of the LORD; though he wist it not, yet is he guilty, and shall bear his iniquity.

“When you come into the land and plant any kind of tree for food, you are to consider the fruit forbidden. It will be forbidden to you for three years; it is not to be eaten.
