¹ sn This is the first occurrence of law (nomos) in Romans. Exactly what Paul means by the term has been the subject of much scholarly debate. According to J. A. Fitzmyer (Romans [AB], 131-35; 305-6) there are at least four different senses: (1) figurative, as a “principle”; (2) generic, meaning “a law”; (3) as a reference to the OT or some part of the OT; and (4) as a reference to the Mosaic law. This last usage constitutes the majority of Paul’s references to “law” in Romans.

³ sn The word is מַלְאָךְ (mal’akh, “messenger, angel”). This angel is to be treated with the same fear and respect as Yahweh, for Yahweh will be speaking in him. U. Cassuto (Exodus, 305-6) says that the words of the first clause do not imply a being distinct from God, for in the ancient world the line of demarcation between the sender and the sent is liable easily to be blurred. He then shows how the “Angel of Yahweh” in Genesis is Yahweh. He concludes that the words here mean “I will guide you.” Christian commentators tend to identify the Angel of Yahweh as the second person of the Trinity (W. C. Kaiser, Jr., “Exodus,” EBC 2:446). However, in addition to being a preincarnate appearance, the word could refer to Yahweh – some manifestation of Yahweh himself.
