For people swear by something greater than themselves, and in all their disputes an oath is final for confirmation. So when God desired to show more convincingly to the heirs of the promise the unchangeable character of his purpose, he guaranteed it with an oath, so that by two unchangeable things, in which it is impossible for God to lie, we who have fled for refuge might have strong encouragement to hold fast to the hope set before us. Hebrews 6:16-18

Note: When Paul says it is impossible for God to lie, he doesn’t just mean it’s extremely unlikely. He means what he says. It’s impossible. God’s very nature is truth and He would not be Himself if He went against it – yet He never changes, so we know that we can trust Him.
