"As it was in their power"

1. Mosiah 18: 25
     25 And there was one day in every week that was set apart that they should gather themselves together to teach the people, and to worship the Lord their God, and also, as often as it was in their power, to assemble themselves together.
2. Alma 52: 13
     13 And thus he was endeavoring to harass the Nephites, and to draw away a part of their forces to that part of the land, while he had commanded those whom he had left to possess the cities which he had taken, that they should also harass the Nephites on the borders by the east sea, and should take possession of their lands as much as it was in their power, according to the power of their armies.
