"In disguise"

1. Mosiah 12: 1
     1 And it came to pass that *after the space of two years that Abinadi came among them in disguise, that they knew him not, and began to ^aprophesy among them, saying: Thus has the Lord commanded me, saying—Abinadi, go and prophesy unto this my people, for they have hardened their hearts against my words; they have repented not of their evil doings; therefore, I will ^bvisit them in my anger, yea, in my fierce anger will I visit them in their iniquities and abominations.
2. Hel. 1: 12
     12 Therefore, Kishkumen was not known among the people of Nephi, for he was in disguise at the time that he murdered Pahoran. And Kishkumen and his band, who had covenanted with him, did mingle themselves among the people, in a manner that they all could not be found; but as many as were found were condemned unto ^adeath.
