They found camels came in the 9th century BC, not the 12th as previously thought.
The findings, described in the journal Tel Aviv, draw more attention to the disagreements between Biblical texts and verifiable history.
"The introduction of the camel to our region was a very important economic and social development,' Dr Ben-Yosef said.
"By analysing archaeological evidence from the copper production sites of the Aravah Valley, we were able to estimate the date of this event in terms of decades rather than centuries," he said.
It is believed that camels were originally domesticated in the Arabian Peninsula for use as pack animals sometime towards the end of the second millennium BC.
The oldest known domesticated camel bones were discovered in the Aravah Valley, in the southern Levant, which runs along the Israeli-Jordanian border from the Dead Sea to the Red Sea and come from a time when the valley was an ancient centre for copper production.
Dr Ben-Yosef dated an Aravah Valley copper smelting camp where the domesticated camel bones were found in 2009 and discovered they dated to between the 11th and 9th century BC.
He led another dig in the area in 2013 to determine exactly when domesticated camels appeared in the southern Levant.
Together with Dr Sapir-Hen, he used radiocarbon dating and other techniques to analyse the findings of these digs as well as several others done in the valley.
In all the digs, they found that camel bones were unearthed almost exclusively in archaeological layers dating from the last third of the 10th century BC or later - centuries after the patriarchs lived and decades after the Kingdom of David, according to the Bible.
The few camel bones found in earlier archaeological layers probably belonged to wild camels, which archaeologists think were in the southern Levant from the Neolithic period or even earlier.
Dr Ben-Yosef and Dr Sapir-Hen think the Aravah Valley and would have been a logical entry point for domesticated camels into the southern Levant as it bordered the Arabian Peninsula.
They believe the first domesticated camels ever to leave the area may be buried in the Aravah Valley.
The arrival of domesticated camels promoted trade between Israel and exotic locations that were previously unreachable.
Camels can travel over much longer distances than the donkeys and mules that preceded them.
By the seventh century BC, trade routes like the Incense Road stretched all the way from Africa through Israel to India.
Camels opened Israel up to the world beyond the vast deserts to profoundly alter its economic and social history, the researchers said.
