And when Moses had completed the term and was traveling with his family, he perceived from the direction of the mount a fire. He said to his family, "Stay here; indeed, I have perceived a fire. Perhaps I will bring you from there [some] information or burning wood from the fire that you may warm yourselves."
So when Moses completed the agreed duration - either eight or ten years - and was returning with his family from Madyan to Egypt, he saw a fire towards the side of Mount Sinai. He said to his family, “Stay here. I have noticed a fire, perhaps I can bring some news to you from it, or a torch of fire with which we can light one for ourselves and get some warmth from the cold.”
