'Common' in the Bible

There was a time when the entire earth spoke a common language with an identical vocabulary.

We're all sons of a common father. We're honest men, your majesty. We're not spies!"

"But your majesty," they pleaded, "your servants include twelve brothers, the sons of a common father back in the land of Canaan. Please! Our youngest brother remains with our father, and the other one is no longer alive."
