The term "lawful" refers to something that is permitted to be done according to a law or other requirement. The opposite of this is "unlawful," which simply means "not lawful."
* In the Bible, something was "lawful" if it was permitted by God's moral law, or by the Law of Moses and other Jewish laws. Something that was "unlawful" was "not permitted" by those laws.
* Depending on the context, ways to translate "lawful" could include "permitted" or "according to God's law" or "following our laws" or "proper" or "fitting."
* The phrase "Is it lawful?" could also be translated as "Do our laws allow?" or "Is that something our laws permit?"
