He Used 'This Night' Only for Warnings
Every time Jesus said 'this night' in the four gospels, something terrible was about to happen to someone in the room.
Across the four gospels, Jesus uses the phrase 'this night' (or 'tonight') in his direct speech on exactly three occasions — and in every instance, the phrase announces an imminent catastrophe directed at or by one of his hearers. In Matthew 26:31, he tells the disciples 'All ye shall be offended because of me this night.' In Matthew 26:34 (paralleled in Mark 14:30 and Luke 22:34), he tells Peter 'this night, before the cock crow, thou shalt deny me thrice.' In Luke 12:20, the rich fool is addressed by God in a parable: 'This night thy soul shall be required of thee.' The phrase never introduces a promise, a comfort, a healing, or a neutral statement. It is purely a marker of sudden reversal or impending loss — either of loyalty (the disciples), of nerve (Peter), or of life itself (the rich fool). What makes this sharper is what 'this night' is never paired with: there is no 'this night you will be healed,' no 'this night the kingdom comes,' no 'this night I will return.' The temporal specificity of the phrase — not 'soon' or 'before long' but 'this night' — appears exclusively in the register of warning. The pattern holds across all four gospels without exception.

Then saith Jesus unto them, All ye shall be offended because of me this night: for it is written, I will smite the shepherd, and the sheep of the flock shall be scattered abroad.
Jesus said unto him, Verily I say unto thee, That this night, before the cock crow, thou shalt deny me thrice.
And Jesus saith unto him, Verily I say unto thee, That this day, even in this night, before the cock crow twice, thou shalt deny me thrice.
And he said, I tell thee, Peter, the cock shall not crow this day, before that thou shalt thrice deny that thou knowest me.
But God said unto him, Thou fool, this night thy soul shall be required of thee: then whose shall those things be, which thou hast provided?
Evidence Notes
Three distinct speeches use 'this night': Matthew 26:31 (all disciples will be offended), Matthew 26:34 / Mark 14:30 / Luke 22:34 (Peter's denial), Luke 12:20 (parable of the rich fool). No instance of 'this night' in Jesus's direct speech is tied to a positive or neutral outcome.
Greek Note
The Greek phrase is 'en tē nukti tautē' (ἐν τῇ νυκτὶ ταύτῃ) in Matthew 26:31 and similar constructions elsewhere. Luke 12:20 uses 'tautē tē nukti' — same words, inverted. In all cases the definiteness of 'this' night (tautē) sharpens the immediacy.
