BOOK OF MORMON - 2 NEPHI 13:9


1830 VERSION

[p.88 ] For Jerusalem is ruined, and Judah is fallen: because their tongues are their doings have been against the Lord, to provoke the eyes of his glory. The shew of their countenance doth witness against them, and doth declare their sin to be even as Sodom, and they cannot hide it. Wo unto their souls! for they have rewarded evil unto themselves. Say unto the righteous, that it is well with them: for they shall eat the fruit of their doings.
