Kehillah in Thessalonika I 5:6-8

Orthodox Jewish Bible

⁶ Therefore, let us not "sleep" as the rest, but let us keep awake with zililut da’as (sober-mindedness).

⁷ For the ones sleeping sleep balailah, and the ones indulging in shichrut (drunkenness) indulge in shichrut balailah.

⁸ But we, being Bnei Yom, let us be bnei zililut da’as (sons of sober-mindedness), having clothed ourselves with the choshen (breastplate) of emunah and ahavah (agape) and as a KOVAH (helmet, YESHAYAH 59:17) the tikvah of Yeshu’at Eloheynu.
