“Then Moses led the people out of the camp to meet with God, and they stood at the foot of the mountain. Mount Sinai was covered with smoke, because the Lord descended on it in fire. The smoke billowed up from it like smoke from a furnace, and the whole mountain trembled violently” (Exodus 19:17-18, NIV).
Mountain Sinai is a holy place where God came, the location that served as the most solemn scene of all, in which God chose to give His Ten Commandments to His people. The top of Jabal Maqla in Saudi Arabia has clear marks of being scorched. Some say that this is an evident that supports the Scriptural verse ‘Mount Sinai was covered with smoke, because the Lord descended on it in fire” (Exodus 19:18, NIV). Some unbeliever says that the scorched marks were due to a volcanic eruption.
It is up to each individual visitor which conclusion he/she will arrive at. Yet it will certainly be a precious moment to vicariously experience by watching the scorched top of the mountain how Moses might have felt when he was climbing up the mountain to meet with God as well as the heart of the people who heard the voice of God in the fire.
