'Strict' in the Bible

Then someone from the army informed him, "Your father put the army under a strict oath saying, 'Cursed be the man who eats food today!' That is why the army is tired."

For the Lord gave me strict orders, 'Do not eat or drink there and do not go home the way you came.'"

For the Lord gave me strict orders, 'Do not eat or drink there; do not go back the way you came.'"
