Final answer:
The major contribution of leisure from Israel is observing the Sabbath, which is a day of rest and religious observance for the Jewish people.
Step-by-step explanation:
The major contribution of leisure from Israel is observing the Sabbath. This practice is deeply rooted in the history and culture of the Jewish people. The Sabbath is the seventh day of the Jewish week and is a day of rest and worship. According to the laws of Moses, Jewish people refrain from work on the Sabbath to remember their escape from slavery in Egypt and to honor God's creation of the world. It is a time for family, community, and religious observance, serving as a cornerstone for Jewish religious life.
