Kim Davis is back at work after serving time in a Kentucky jail for refusing to issue marriage licenses because of her religious beliefs. But her cause will now be fought out on billboards.

A billboard near the Rowan County clerk’s office where she works reads, “Dear Kim Davis, the fact that you can’t sell your daughter for three goats and a cow means we’ve already redefined marriage.”

The sign is in reference to the Bible verse Exodus 21:7, which states, “If a man sells his daughter as a servant, she is not to go free as male servants do.” The scripture does not mention farm animals of any variety, but it refers to the fact that a male Jew sold into service to pay a debt was released after seven years, but a master could marry his female slave, meaning she stayed for life.

The billboard is the work of Planting Peace, a nonprofit organization that describes its aim as “spreading peace in a hurting world.” The organization’s president told NBC News the billboard cost $500 and will remain on the Rowan County road for one month. Planting Peace released a statement to explain the Biblical reference. The movement against LGBT marriage, the statement reads, uses a “rigid interpretation” of scripture to pick and choose what they wish to condemn while ignoring scriptures with social practices no group in 21st-century America condones.
