Manna is a substance described in the Bible, specifically in the books of Exodus and Numbers. It is said to have appeared as small, white flakes on the ground, providing food for the Israelites during their 40 years of wandering in the desert after escaping from Egypt. Manna is often depicted as a miraculous provision from God to sustain the people. The characteristics of manna are described as being sweet like honey and having a taste similar to wafers. It was collected each morning, and the Israelites were instructed to gather only what they needed for the day, as it would spoil if kept overnight. This practice emphasized reliance on divine provision.
