JMNT(i)
1 But concerning the times and the fitting situations (or: specific seasons or occasions; fertile periods; mature moments), brothers (= fellow believers), you have no need [for it] to be continually written to you,
2 for you yourselves are accurately aware (know exactly from having seen) that a day of, from and which is the Lord [= Yahweh] thus continually comes (is habitually and repeatedly coming and going; is presently coming) as a thief in a night (or: within [the] night). [comment: the day of Yahweh was a term that figured a time of judging and hard times, in the Old Testament; e.g., cf Joel 1:15 and 2:1-2; Jer. 30:7; Amos 5:18; Zeph. 1:14-18]
3 So whenever they may be repeatedly saying, "Peace and security from falling (or: safety; stability), " then (at that time) sudden and unexpected ruin (or: a surprise of destruction) is presently standing upon them, just as the birth-pang for the pregnant woman (or: to the one having [a child] in the womb), and they may by no means flee out or make an escape.
