Deuteronomio 23

You shall observe and do that which has gone out of your lips. Whatever you have vowed to the LORD your God as a free will offering, which you have promised with your mouth, you must do.

Guardarás lo que tus labios pronunciaren; y harás, como prometiste á Jehová tu Dios, lo que de tu voluntad hablaste por tu boca.

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.
