Rachamim was born  1931 in Yemen to Sa’adya and Yemima Chana. In 1933, when Rachamim was still an infant, the family made Aliyah and settled in Tel-Aviv. Rachamim studied at “Yessod-Hama’alah” school, and joined the Beitar movement. He received a nationalist education and wanted to fight in the battle to free the Land of Israel from the foreign occupier, Britain, and establish a free independent Jewish State. In the  midst of 1947, while still a student, he joined Lehi. Like many others who joined the movement, he was placed in the Youth Division and distributed info-bulletins and info-materials. The  Arabs attacked vehicles along the roads and in civilian towns and settlements. They besieged Jerusalem. Rachamim underwent a weapons training course at Sheikh-Mounis Lehi base, north of Tel-Aviv; the former Arab residents had escaped and Lehi established a military base for weapons and training, as well as supplies intended for Lehi fighters in Jerusalem (which, according to the UN, wasn’t included in the Jewish State’s borders). Rachamim  was tasked a number of times  to accompany jeeps  making their way to Jerusalem, to deliver supplies and ammunition. They drove via the difficult mountainous bypass road  nicknamed the “Burma Road”’.

Rachamim joined the IDF and fought in the War of Independence. Later, as a reserves soldier he fought in the Sinai Campaign, in the Six Day War and the in the Yom Kippur War.

After the War of Independence he married Leah and they had two daughters. Later he married Bruria and they had a son and daughter. Rachamim has nine grandchildren. On 20.01.1982 he married for the third time, to Yedida Avraham. After his discharge, he earned his living as a cinema usher. Later he worked in real-estate with his father. He afterwards ran the family real-estate office. Rachamim was an active Likud party member. He passed away on January 20,2001  and was laid to rest in the Yarkon Cemetery.
