Mosiah 24:19

And in the morning the Lord caused a deep sleep to come upon the Lamanites, yea, and all their task-masters were in a profound sleep.

In the morning, the Lord made the Lamanites fall into a deep sleep. All their bosses were also in a deep sleep.

In the morning, the Lord caused a deep sleep to fall on the Lamanites. All their overseers were in a profound sleep.
