Jacob 3:12

And now I, Jacob, spake many more things unto the people of Nephi, warning them against fornication, and lasciviousness, and every kind of sin, telling them the awful consequences of them;

I said many more things to Nephi’s people. I warned them against sexual sins and every kind of sin. I told them the terrible things that would happen because of these sins.

I spoke many more things to the people of Nephi that day, warning them against sexual sin, lust, and every kind of wrong—telling them the terrible consequences.
