According to the Book of Mornon, who was the first person to speak in tongues?
King Lamoni's wife
And it came to pass that she [Abish] went and took the queen [King Lamoni's wife] by the hand, that perhaps she might raise her
from the ground; and as soon as she touched her hand she arose and stood upon her feet, and cried with a loud
voice, saying: O blessed Jesus, who has saved me from an awful hell! O blessed God, have mercy on this people!
And when she had said this, she clasped her hands, being filled with joy, speaking many words which
were not understood.
Alma 19:29This was in 90 BCE (according to the footnote in the Book of Mormon) -- about 90 years before Jesus was born and more
than 120 years before the Holy Spirit was supposedly given to Jesus's disciples.
