'Improper' in the Bible

For the Lord your God walks throughout your camp to protect you and deliver your enemies to you; so your encampments must be holy. He must not see anything improper among you or He will turn away from you.

“If a man marries a woman, but she becomes displeasing to him because he finds something improper about her, he may write her a divorce certificate, hand it to her, and send her away from his house.

So turn and leave in peace. You must not do anything that the leaders of the Philistines consider improper!"

You are offering improper sacrifices on my altar, yet you ask, 'How have we offended you?' By treating the table of the Lord as if it is of no importance!

May the Lord cut off from the community of Jacob every last person who does this, as well as the person who presents improper offerings to the Lord who rules over all!
