'Legal' in the Bible

But to the elders he said, “Wait here for us until we return to you. And behold, Aaron and Hur are with you; whoever has a legal matter, let him approach them.”

There was a widow in that city, and she kept coming to him, saying, ‘Give me legal protection from my opponent.’

yet because this widow bothers me, I will give her legal protection, otherwise by continually coming she will wear me out.’”
