having drunk old wine

Luke 5:36-39

And he spake also a parable unto them; 

No man putteth a piece of a new garment upon an old; 

if otherwise, then both the new maketh a rent, and the piece that was taken out of the new agreeth not with the old.

And no man putteth new wine into old bottles; else the new wine will burst the bottles, and be spilled, and the bottles shall perish.

But new wine must be put into new bottles; and both are preserved. 

No man also having drunk old wine straightway desireth new: for he saith, "The old is better."

(whilst drunk they cannot perceive the difference between the holy and unholy, and between unclean and clean Leviticus 10:9-10)
