Thank you all for your comments. I do agree that polygamy never ended well in the Bible. Some of my confusion still stems from the fact that sexually immoral people are cast into the lake of fire- But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death. Revelation 21:8. So, in that light, are Jacob, David, Solomon, etc. included in that group and if so, they will also be cast into the lake of fire?
