'Otherwise' in the Bible

O royal family descended from David. The Lord says: 'See to it that people each day are judged fairly. Deliver those who have been robbed from those who oppress them. Otherwise, my wrath will blaze out against you. It will burn like a fire that cannot be put out because of the evil that you have done.

Then Johanan son of Kareah spoke privately to Gedaliah there at Mizpah, "Let me go and kill Ishmael the son of Nethaniah before anyone knows about it. Otherwise he will kill you and all the Judeans who have rallied around you will be scattered. Then what remains of Judah will disappear."
