5. Mose 23:23

[23:24] Aber was zu deinen Lippen ausgegangen ist, sollst du halten und darnach tun, wie du dem HERRN, deinem Gott, freiwillig gelobt hast, was du mit deinem Munde geredet hast.

That which is gone out of thy lips thou shalt keep and perform; even a freewill offering, according as thou hast vowed unto the LORD thy God, which thou hast promised with thy mouth.
