This is the blessing of the challah translated into sign language. Challah is the special twisted loaf of bread eaten on Shabbat. We sing the  b'rachah ( blessing) expressing thanks to God before eating any food. It represents a recognition that people owe a measure of gratitude to God for providing food for all living things.
