JMNT(i)
16 "Now whenever you may periodically fast, do not proceed to become sad-faced or stern, gloomy people – as the overly judging and critical folks [see vs. 2, above] for they habitually remove the light from (or: disguise or distort) their faces so that they can continue to be visible to people (or: be manifested for mankind and appear) [as] ones in the process of fasting. I continue saying to you truly: They are presently holding their full payment!
17 "So you folks, during fasting anoint, rub and massage your head, then wash your face (= groom yourself),
18 "so that you would not appear to people (or: may not be visible for mankind) [to be] in the midst of fasting, but rather, to (or: for) your Father – the One within the hidden [sphere; place]. And your Father – the One continuously seeing within the hidden [sphere; place] – will continue giving [something] back to (for; in) you!
