How it's used
This idiom is almost exclusively used in a metaphorical or ironic sense today to describe a very serious, solemn, or dramatic promise between people. It carries a heavy, archaic tone that makes it sound overly theatrical when applied to modern business or personal relationships. Use it when you want to emphasize the gravity of a pact or to mock the excessive seriousness of a situation.
Examples
They swore an oath in blood back then, who knew they would end up turning against each other.
