'Otherwise' in the Bible

Then they said, "Come, let's build ourselves a city and a tower with its top in the heavens so that we may make a name for ourselves. Otherwise we will be scattered across the face of the entire earth."

Judah said, "Let her keep the things for herself. Otherwise we will appear to be dishonest. I did indeed send this young goat, but you couldn't find her."

I will provide you with food there because there will be five more years of famine. Otherwise you would become poor -- you, your household, and everyone who belongs to you."'
