Jews eat fish on Fridays for many reasons. Firstly, it is a reminder of the stories in the Torah about Elijah and Jonah, who were both saved from danger by fish. Secondly, it is symbolic of the ancient Israelites’ migration to freedom through the Red Sea. Furthermore, some believe that eating fish on Fridays may even bring good luck in business matters. Lastly, it provides an alternative to forbidden foods such as pork, which cannot be eaten according to kosher law. As such, eating fish has become part of Jewish culture and tradition during this holy day.
