What is lightning from heaven in hebrew?

Lightning from heaven in Hebrew is referred to as ברק מן השמים (Barak Min Hashamayim). The word ברק (Barak) specifically means lightning or a bright flash of light, and the word שמים (Hashamayim) means heaven or the sky.

Lightning has symbolic and spiritual significance in Hebrew culture, representing the power and glory of God. In the Bible, thunder and lightning were often used to signify the presence of God, such as during the giving of the Ten Commandments on Mount Sinai.

In Jewish tradition, lightning is powerful and unpredictable, and it's believed to have the ability to either harm or protect individuals. Therefore, Jewish people recite special prayers and Psalms during thunderstorms to ward off evil and ask for protection from harm.
