Matthew 6:18

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.

so that you are not seen by men to be fasting, but by your Father who is in secret, and your Father, who sees in secret, will reward you.

that thou be not seen of men to fast, but of thy Father who is in secret: and thy Father, who seeth in secret, shall recompense thee.

that thou mayest not appear to men fasting, but to thy Father who `is' in secret, and thy Father, who is seeing in secret, shall reward thee manifestly.

so that your fasting will not be obvious to men, but only to your Father, who is unseen. And your Father, who sees what is done in secret, will reward you.
