Here is your short paragraph on Jewish festivals:
Judaism evolved over many centuries before the common Era through the people known as the Israelites.
The genesis of Jewish religion goes back to Abraham (the father of the people) who was born in Ur of the Chaldees (Babylonia -modern Iraq) approximately 4,000 years ago.
He conceived the idea of Monotheism, the oneness of an invisible God (and the brotherhood of man), demanding as the creator of heaven and earth, absolute obedience to His will and divine dictates for the good of mankind. Prayers play a vital role in Judaism and synagogne is a place of Jewish worship. Indian Jewry now numbers not more than 7,000 in the whole country and they have been in India for well over 2,000 years.
The most significant festivals observed by them are Purim (Festival of Lots), Passover (Pesah), Shebuoth (Festival of Weeks), Tisha-Be-Av (Fast of the Ninth of Av) Rosh-ha-Shana (New Year’s Day), Yom Kippur (Day of Atonement), Feast of Booths, Rejoicing over the Torah Simhath Torah and Hannukah (Feast of the Dedication).
