"Ought ye not to tremble"

1. Mosiah 15: 27
     27 Therefore ought ye not to tremble? For salvation cometh to none such; for the Lord hath redeemed none such; yea, neither can the Lord redeem such; for he cannot deny himself; for he cannot deny ^ajustice when it has its claim.
2. Mosiah 16: 13
     13 And now, ought ye not to tremble and repent of your sins, and remember that only in and through Christ ye can be saved?
