Mt 6:16-18 (King James)

¹⁶ Moreover when ye fast, be not, as the hypocrites, of a sad countenance: for they disfigure their faces, that they may appear unto men to fast. Verily I say unto you, They have their reward.
¹⁷ But thou, when thou fastest, anoint thine head, and wash thy face;
¹⁸ That thou appear not unto men to fast, but unto thy Father which is in secret: and thy Father, which seeth in secret, shall reward thee openly.

Mt 6:16-18 (Vulgate)

¹⁶ Cum autem jejunatis, nolite fieri sicut hypocritæ, tristes. Exterminant enim facies suas, ut appareant hominibus jejunantes. Amen dico vobis, quia receperunt mercedem suam.
¹⁷ Tu autem, cum jejunas, unge caput tuum, et faciem tuam lava,
¹⁸ ne videaris hominibus jejunans, sed Patri tuo, qui est in abscondito : et Pater tuus, qui videt in abscondito, reddet tibi.
