Nehemiah 4:19-23

Then I said to the nobles, the rulers, and the rest of the people, “The work is great and extensive, and we are separated far from one another on the wall. Wherever you hear the sound of the trumpet, rally to us there. Our God will fight for us.” So we labored in the work, and half of the men held the spears from daybreak until the stars appeared. At the same time I also said to the people, “Let each man and his servant stay at night in Jerusalem, that they may be our guard by night and a working party by day.” So neither I, my brethren, my servants, nor the men of the guard who followed me took off our clothes, except that everyone took them off for washing.
