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 19:29-30

This 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.
