The text closest to Hebrew language is proto Canaanite not known to exist before ~900 - 1000 BCE, establishing the link between earlier Canaanite cuneiform texts and phonetic language and later Hebrew language.
Biblical Hebrew has been written with a number of different writing systems. The Hebrews adopted the Phoenician script around the 12th century BCE, which developed into the Paleo-Hebrew script. This was retained by the Samaritans, who use the descendent Samaritan script to this day
In its earliest stages Biblical Hebrew was not highly differentiated from Ugaritic and Amarna Canaanite.
The inscription on a pottery shard dating to 1000 BC parallels but does not cite sections of the Bible.

Just as an aside: The existence of Jezebel (circa 900BC) is confirmed.
