18 Further, the disciples of John as well as the Pharisees are habitually practicing (or: are in the process of) fasting [note: a ritual of abstaining from food from 6:00 a.m. to 6:00 p.m., after which normal food could be eaten]. So these kept on coming to Him, saying, "Why (Through what [circumstance]) are the disciples of John and the disciples of the Pharisees habitually fasting (or: currently observing a fast), yet your disciples are not habitually (or: currently) fasting?"
19 Consequently, Jesus said to them, "Is it now possible for the sons of the wedding hall (= the bridegroom's friends and guests) to be fasting in the [situation] in which (or: = while) the bridegroom continues being with them? No, they continue unable to start or to continue fasting (or: there can be no fasting) so long as (or: for whatever time) they continue having the bridegroom with them!
20 "Yet days will be coming when the bridegroom may be taken away from them, and then – in that day – they will proceed in fasting.
21 "No one usually sews a patch of an unshrunk shred of cloth upon an old and worn out cloak (coat; outer garment). Yet, if [he does], is not the filling-result ( the [patch] that fills up [the hole]) progressively lifting up away from it – the new (fresh) one from the old one – and a worse split-effect (or: tear; rip) is gradually happening?
22 "Further, no one normally pours new wine into old and worn out leather bottles (wineskins). Yet, if [he does], will not the wine proceed in bursting and ripping the leather bottles (wineskins), and the wine be progressively lost – as well as the wineskins (bottles)? To the contrary, new (= newly made) wine [is put] into new (fresh, just beginning to be used) wineskins (leather bottles)."
