Career
Born David Borovoi in Nizhyn in the Russian Empire (today in Ukraine), Bar-Rav-Hai joined the Zionist Students Organization in Odessa. In 1911, he moved to Germany, but returned to Russia in 1918 and joined the Young Zion movement, becoming secretary of the Jewish community in Odessa, until the Soviet authorities closed it down in 1920. Afterwards he joined the Zionist underground, and was arrested in 1922.
He was sentenced to two years in prison, but was released after 15 months and expelled from the country.
In 1924, he made aliyah to Mandatory Palestine, where he joined Hapoel Hatzair. In 1933, he established a law office in Haifa.
As chairman of Israel’s election committee in October 1948, he wrote that the need to hold elections within a short period of time made it impossible to create voting districts. Therefore, the whole country was one district for the purpose of the first elections for the Knesset, but with proportional representation.
He argued in favor of delaying writing a formal constitution and drafting it "step by step..chapter by chapter," with the Israeli Declaration of Independence as its cornerstone.
He was re-elected in 1951, but lost his seat in the 1955 elections. However, he re-entered the Knesset on 24 October 1956 as a replacement for Senetta Yoseftal. He was re-elected in 1959 and 1961, serving until 1965.
He was placed 115th place on the Alignment list in 1965 elections.
