Out of the north - From this quarter the Assyrian conquerors came upon the holy land. The vision, though seen in Chaldaea, had reference to Jerusalem, and the seer is to contemplate judgment as it is coming upon the holy land. Others consider the words expressive of the special seat of the power of Yahweh. The high mountain range of Lebanon that closed in the holy land on the north naturally connected to the inhabitants of that country the northern region with the idea of height reaching to heaven, from which such a vision as this might be supposed to come.
Infolding itself - Forming a circle of light - flames moving round and round and following each other in rapid succession, to be as it were the framework of the glorious scene.
Amber - The original word occurs only in Ezekiel. The Septuagint and the Vulgate have “electrum,” a substance composed by a mixture of silver and gold, which corresponds very well to the Hebrew word. The brightness, therefore, is that of shining metal, not of a transparent gum. Render it: “out of the midst thereof,” like Ezekiel 1:7 burnished gold out of the midst of fire.
