'Foot of the Mountain' in the Bible

Then Moses brought the people out of the camp to meet God, and they stood and presented themselves at the foot of the mountain.

Moses wrote down all the words of the Lord. Then he got up early in the morning, and built an altar [for worship] at the foot of the mountain with twelve pillars (memorial stones) representing the twelve tribes of Israel.

And as soon as he approached the camp and he saw the calf and the dancing, Moses’ anger burned; and he threw the tablets from his hands and smashed them at the foot of the mountain.
