Answer:
Leviticus 24-44:46.
Explanation:
The Hebrew Bible mentions few rules and regulations for maintaining slaves and how to treat them. Some provisions of the Hebrew Bible talks about setting slaves free after specific years while some talks about keeping them for generations.
The provision that might discourage many Hebrew slaves from seeking their freedom would be through the contents of Leviticus 24-44:46 of the Hebrew Bible. It says that slaves can be acquired from other nations or from one's own land itself if one wills to do so. The slaves that one acquire become one's private property and can be inherited to one's children.
This interprets that slaves have no right to become free if the owner does not wants to set them free. Instead they can be inherited by the owner's children as their property.
