This is clear from the meaning of 'night' as a state of obscurity so far as the truth and good of faith are concerned, dealt with in 1712, 6000.

The fact that this was told to the disciples means that it was addressed to all who belonged to the Church, for the twelve disciples represented these, 2089, 2129, 2130. This explains why they are told, See that no one leads you astray, and also, When you hear of wars and rumours of wars, see that you are not alarmed.
