1 Nephi 8:11-12 - Alma 36:24

1 Nephi 8

11 And it came to pass that I did go forth and partake of the fruit‍ thereof; and I beheld that it was most sweet, above all that I ever before tasted. Yea, and I beheld that the fruit thereof was white, to exceed all the whiteness‍ that I had ever seen.
12 And as I partook of the fruit thereof it filled my soul with exceedingly great joy; wherefore, I began to be desirous‍ that my family should partake of it also; for I knew that it was desirable‍ above all other fruit.

Alma 36:24

24 Yea, and from that time even until now, I have labored without ceasing, that I might bring souls unto repentance; that I might bring them to taste‍ of the exceeding joy of which I did taste; that they might also be born‍ of God, and be filled‍ with the Holy Ghost.
