Alma 62:23

And it came to pass that they were all let down into the city by night, by the means of their strong cords and their ladders; thus when the morning came, they were all within the walls of the city.

They were all let down into the city by night using their strong ropes and ladders. When morning came, they were all inside the walls of the city.

Under cover of night, they all descended into the city using their ropes and ladders. By morning, they were all inside the walls.
