Deuteronomio 23

Pero lo que hubiere salido de tus labios, lo guardarás y lo cumplirás, conforme lo prometiste a Jehová tu Dios, pagando la ofrenda voluntaria que prometiste con tu boca.

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.

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.
