Born in Mezhirichi in the Russian Empire (today in Ukraine), Arazi was educated at a gymnasium in Poland, before studying law in Warsaw, where he was certified as a lawyer. He also graduated from the Judaic Studies Institute in the city. Whilst a student he was amongst the leadership of the Socialist Zionist student movement, and also joined Hashomer Hatzair.
Between 1933 and 1939, he worked in the Tarbut school system, but in 1940, following the Soviet invasion of Poland, was exiled to the Urals by the Soviet authorities. He returned to Poland in 1946 and re-established Hashomer Hatzair, becoming its secretary general. He was also involved with the Jewish National Fund, becoming a member of its board of directors.
In 1949, he made aliyah to Israel, where he joined Mapam, which had been formed by a merger of the Hashomer Hatzair Workers Party and the Ahdut HaAvoda Poale Zion Movement. In 1959, he became the party's political secretary, a role he held until 1965 when he was elected to the Knesset on the party's list. He was re-elected in 1969 (by which time Mapam had formed the Alignment alliance), and was appointed Deputy Speaker of the Knesset. He lost his seat in the 1973 elections.
He died in 1983 at the age of 76.
