17:26

the days of Noah: In the Bible, the term “day(s) of” is sometimes used with reference to the time period of a particular person. (Isa 1:1; Jer 1:2, 3; Lu 17:28) Here “the days of Noah” are compared to the days of the Son of man. In a similar statement recorded at Mt 24:37, the term “the presence of the Son of man” is used. Jesus does not limit the comparison just to the coming of the Flood as a final climax during Noah’s days, though he shows that his “days” or “presence” will see a similar climax. “The days of Noah” actually covered a period of years, so there is basis for believing that the foretold “days [or, “presence”] of the Son of man” would likewise cover a period of years, being climaxed by the destruction of those who do not seek deliverance.​—See study note on Mt 24:3.
