Manna is a substance described in the Bible, specifically in the book of Exodus, as food provided by God to the Israelites during their journey in the desert. It is often depicted as a sweet, flaky substance that appeared on the ground each morning, allowing the people to gather it for sustenance. In addition to its biblical significance, manna has also been used in various cultures to refer to any unexpected or miraculous provision. The term has evolved to symbolize a blessing or a source of nourishment that comes at just the right time, often in difficult circumstances.
