Ether 15:24

And it came to pass that they slept upon their swords that night, and on the morrow they fought again, and they contended in their mights with their swords, and with their shields, all that day;

That night they slept on their swords. The next day they fought again. They fought as hard as they could with their swords and shields all day.

They slept on their swords that night. The next morning they fought again, battling fiercely with swords and shields all day long.
