Take upon themselves

1. Mosiah 15: 9
     9 Having ascended into heaven, having the bowels of mercy; being filled with compassion towards the children of men; standing betwixt them and justice; having broken the bands of death, taken upon ^ahimself their iniquity and their transgressions, having redeemed them, and ^bsatisfied the demands of justice.
2. Mosiah 25: 12
     12 And it came to pass that those who ^awere the children of Amulon and his brethren, who had taken to wife the ^bdaughters of the Lamanites, were displeased with the conduct of their fathers, and they would no longer be called by the names of their fathers, therefore they took upon themselves the name of Nephi, that they might be called the children of Nephi and be numbered among those who were ^ccalled Nephites.
3. Hel. 11: 24
     24 And it came to pass that in the *eightieth year of the reign of the judges over the people of Nephi, there were a certain number of the dissenters from the people of Nephi, who had some years before gone over unto the Lamanites, and taken upon themselves the name of Lamanites, and also a certain number who were real descendants of the Lamanites, being stirred up to anger by them, or by those dissenters, therefore they commenced a ^awar with their brethren.
4. D&C 101: 45
     45 And set ^awatchmen round about them, and build a tower, that one may overlook the land round about, to be a watchman upon the tower, that mine olive-trees may not be broken down when the enemy shall come to spoil and take upon themselves the fruit of my vineyard.
