Alma 25:15

yea, and they did keep the law of Moses: for it was expedient that they should keep the law of Moses as yet, for it was not all fulfilled. But notwithstanding the law of Moses, they did look forward to the coming of Christ, considering that the law of Moses was a type of his coming, and believing that they must keep those outward performances, until the time that he should be revealed unto them.

They kept the law of Moses. It was important for them to keep the law of Moses because not everything had happened yet. But even though they followed the law of Moses, they looked forward to when Christ would come. They understood that the law of Moses was a picture of his coming. They believed they had to keep doing these practices until Christ would be shown to them.

They kept the law of Moses too—it was still necessary since everything in it hadn’t been fulfilled yet. But even as they kept the law of Moses, they looked forward to Christ’s coming. They understood the law was pointing toward him, and they knew they had to keep these outward practices until he appeared.
