Then let our countenances be looked upon before thee, and the countenance of the children that eat of the portion of the king's meat: and as thou seest, deal with thy servants.

And at the end of ten days their countenances appeared fairer and fatter in flesh than all the children which did eat the portion of the king's meat.

'And when ye may fast, be ye not as the hypocrites, of sour countenances, for they disfigure their faces, that they may appear to men fasting; verily I say to you, that they have their reward.
