Alma 18:9

And they saith unto him, Behold, he is feeding thy horses.—Now the king had commanded his servants previous to the time of the watering of their flocks, that they should prepare his horses and chariots, and conduct him forth to the land of Nephi: for there had been a great feast appointed at the land of Nephi, by the father of Lamoni, who was king over all the land.

They said to him, “He is feeding your horses.” Before the time of watering their flocks, the king had told his servants to get his horses and chariots ready. He wanted them to take him to the land of Nephi. Lamoni’s father was king over all the land. He had planned a great feast in the land of Nephi.
