Gethsemani is a place mentioned in the Bible, specifically in the New Testament. It is the garden where Jesus and his disciples went to pray after the Last Supper, prior to his crucifixion. Gethsemani is located on the Mount of Olives, just outside the city walls of Jerusalem. The word Gethsemani is derived from the Hebrew word "Gat Shemanim," meaning "olive press," which refers to the pressing of olives to make oil. The significance of Gethsemani lies in its association with Jesus' agony and apprehension before his arrest, as described in the Gospel accounts.
