Leviticus 19:12
““‘You shall not swear by my name falsely, and profane the name of your God. I am Yahweh.”
What does Leviticus 19:12 mean?
When you make a promise in God's name, you're putting his reputation on the line along with your own. Speaking falsely while invoking God's name treats something sacred as casual or disposable, essentially making God a co-signer of a lie. What matters here isn't just avoiding outright perjury in court, but being honest in all your commitments, especially the serious ones where you call on God as a witness. The simple closing "I am Yahweh" reminds us that God himself is present and aware, watching how we use his name and keep our word.
