YARMULKES bob as voices swell in a sacred song carried from Biblical times to the scenic fields of a far-flung Zimbabwean village that is home to a "lost tribe" of Israel.
"We have been singing this song for about 2,600 years. It's an old, old song," said Perez Hamandishe, wearing a white crocheted skullcap with a blue Star of David, standing in a small village near Gutu, some 200 kilometers south of the capital Harare.
He is a member of the country's Lemba tribe, which still observes Jewish traditions. DNA evidence from tribe members show that these traditions were brought here from the Middle East thousands of years ago.
The secretive Lemba observe strict rules that have more in common with norms in Jerusalem than Harare: a ban on pork, ritual slaughter of livestock and male circumcision.
They see themselves as southern Africa's tribe of "black Jews" who have honoured their Semitic roots for centuries, despite converting to faiths including Christianity and Islam.
Their oral histories have been borne out by their genes: Unlike other groups with similar claims, the Lemba can point to genetic proof of links to the eastern Mediterranean. Causing a splash in the late 1990s, tests showed that around 55 percent of Jews named Cohen shared an ancestor from the Biblical time of Moses - and that a Lemba clan did as well.
"They also shared this ancestor who lived about 3,000 years ago in the Middle East," said Lemba expert Tudor Parfitt. "It's a very interesting genetics story, and it's a very interesting human story in that the genetics supports the [Lemba's] very passionate belief."
There is no written history of their forefathers' passage to what is now Zimbabwe, but the Lemba believe their forefathers arrived with a replica ark - known as the ngoma lungundu - that went missing.
The Lemba say they are descendants of white men who came from a place believed to be modern Yemen. But their ties to Judaism are cultural and not religious, they say.
"If you remove Judaism, you have removed our culture," said Hamandishe, a Member of Zimbabwe's Parliament. "So we know Judaism as a culture, not as a religion.
"We tried to tell everyone about us, but people wouldn't believe it. But now that hard science has proved it, we are now happy that what we have been telling them has come to be the truth," said Hamandishe, who has visited Israel.
Views are mixed on taking advantage of Israel's "right of return," ranging from enthusiasm over settling in the Jewish state to reluctance over being uprooted and having to find a new home and learn a new language.
Numbering around 70,000, Lemba are also found in upper South Africa and share customs that are kept secret from the outside world.
"Lemba is culture," said Shepherd Tseisi, the son of the chief in Mberengwa, another Lemba stronghold further south in Zimbabwe, reached via a bone-rattling drive down dirt roads that wind deep into the countryside.
"Because of our movements and the environment that we live in, some of our cultural activities tend to change. But the concept of being a Lemba ... that's the same."
Tribe members, who claim to have built Great Zimbabwe, a medieval stone city now in ruins that is a UNESCO World Heritage Site, have managed to prevent their customs from being absorbed or wiped out by dominant local or colonial cultures.
"Because of the passing of time, quite a number of things were forgotten, but very important things were actually remembered," said local headmaster Jacob Nyikavaranda, one of the elders who act as custodians of Lemba history.
"We are using Shona because Shona is now our local language. We have forgotten our original language (Hebrew)," Hamandishe said. The Lemba have also relaxed a ban on marrying outside the tribe.
While similar communities with Judaic identities exist in Africa, the Lemba have science in their corner.
"I think it's fair to say that in absolutely the whole of Africa, they are unique because there are plenty of other tribes, many, many, many other tribes throughout Africa, who claim to have Israelite origins," Parfitt said.
"But the (Lemba ) are the only tribe who claim to have Israelite origins who've actually got any genetic proof. There is this very strong DNA evidence that they came from the eastern Mediterranean," he said.
"But they're black, they're a fairly well-integrated part of southern African society, they speak only local languages and they're Christians for the most part, so their identity is very complicated. And quite what they make of it in the future ... we'll have to see."
