how did the written Hebrew language survive the Bronze Age Collapse?

As a heads up, this is a good candidate for the "Short Answers to Simple Questions" thread. There is little that can be said on this topic, as there are no Hebrew texts that date to the Bronze Age. The earliest Phoenician, Aramaic, and Hebrew texts - such as the Ahiram sarcophagus inscription, the Gezer Calendar, the Khirbet Qeiyafa ostracon, and the 'Izbet Sartah ostracon - date to the Early Iron Age.

For more on this, I recommend the chapter "Early Hebrew Writing" in A Social History of Hebrew by William Schniedewind.

Thank you; but what was the Bible written in then? And how could we decipher it?
