Book of Mormon, Book of Jacob

15 And now it came to pass that the people of Nephi, under the reign of the second king, began to grow hard in their hearts, and indulge themselves somewhat in wicked practices, such as like unto David of old desiring many wives and concubines, and also Solomon, his son. (Jacob 1:15)

24 Behold, David and Solomon truly had many wives and concubines, which thing was abominable before me, saith the Lord. (Jacob 2:24)
