'At His Presence' in the Bible

And Joseph said to his brethren, I am Joseph. Does my father yet live? And his brethren could not answer him, for they were troubled at his presence.

Therefore am I troubled at his presence; I consider, and I am afraid of him.

The burden of Egypt. Behold, Jehovah rideth upon a swift cloud, and cometh to Egypt; and the idols of Egypt are moved at his presence, and the heart of Egypt melteth in the midst of it.

The mountains quake before him, and the hills melt, and the earth is upheaved at his presence, and the world, and all that dwell therein.
