Trust in the Lord with all your heart, and do not rely on your own insight. In all your ways acknowledge him, and he will make straight your paths. (Proverbs 3:5-6)
Jesus said to his disciples: “You have heard that it was said to your ancestors, Do not take a false oath, but make good to the Lord all that you vow. But I say to you, do not swear at all…” Matthew 5:33–34
