1 Thessalonians 5:4-6

Authorized (King James) Version

⁴ But ye, brethren, are not in darkness, that that day should overtake you as a thief. ⁵ Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness. ⁶ Therefore let us not sleep, as do others; but let us watch and be sober.
