Lying "for good"--Rahab as justification for Christian's right to lie in difficult circumstances?

Hi everyone! God bless you. I'm part of a bible study with several visitors who think differently on the topic of lying. We recently discussed Jesus' teaching on swearing oaths and the topic of honesty came up. The perspective one of the visitors defended was that the Christian standard should always be to tell the truth, but there are occasions when/where lies can be the better option. Rahab deceiving her king to hide the Israelite messengers was one example, and Corrie Ten Boom's family's incredible efforts to protect Jews during the holocaust by hiding them and lying about it was another. My own take was that Rahab was praised because she hid the spies, not because she used lying or deceit to do so. I also felt that, like Rahab, Corrie Ten Boom's family's efforts are to be commended, but this doesn't mean every choice they made along the way was justified by the teachings of Jesus. Some would argue honesty would have jeopardized the lives of the Israelite spies and the persecuted Jews, and this isn't a small matter. But, I argued lying/deceiving and telling everything you know about the people you're trying to protect, aren't the only options available to us. Jesus remained silent before His accusers. This is another option for us too. Or, maybe there are other options as well: fleeing, hiding, remaining silent, avoiding the authorities as much as possible, and maybe other options? Would love to hear any thoughts you might have in order to better understand this topic, and improve my ability to help others do the same. Also, would love additional scripture references and maybe other stories about faithfulness in this area of life in the lives of Christians throughout history. Thank you!
