Luke 21:34-37

“But be on guard, so that your hearts are not weighed down and depressed with the giddiness of debauchery and the nausea of self-indulgence and the worldly worries of life, and then that day [when the Messiah returns] will not come on you suddenly like a trap; for it will come upon all those who live on the face of all the earth. But keep alert at all times [be attentive and ready], praying that you may have the strength and ability [to be found worthy and] to escape all these things that are going to take place, and to stand in the presence of the Son of Man [at His coming].” Now in the daytime Jesus was teaching in [the porches and courts of] the temple, but at night He would go out and spend the night on the mount that is called Olivet.
