Judges 11:31

then whatever comes out the door of my house to greet me on my triumphant return from the Ammonites will belong to the LORD, and I will offer it up as a burnt offering.”

Then it shall be, that whatsoever cometh forth of the doors of my house to meet me, when I return in peace from the children of Ammon, shall surely be the LORD’s, and I will offer it up for a burnt offering.
