Alma 17:32

And it came to pass that they went in search of the flocks, and they did follow Ammon, and they rushed forth with much swiftness, and did head the flocks of the king, and did gather them together again, to the place of water.

So they went to look for the flocks. They followed Ammon. They rushed forward very quickly. They got ahead of the king’s flocks and gathered them together again at the water.

They went searching for the flocks and followed Ammon’s lead. Moving fast, they got ahead of the animals and herded them back to the watering place.
