Exodus 23:21-22

23:21 Take heed because of him, and obey his voice; do not rebel against him, for he will not pardon your transgressions, for my name ¹  is in him. 23:22 But if you diligently obey him ²  and do all that I command, then I will be an enemy to your enemies, and I will be an adversary to your adversaries.

¹ sn This means “the manifestation of my being” is in him (S. R. Driver, Exodus, 247). Driver quotes McNeile as saying, “The ‘angel’ is Jehovah Himself ‘in a temporary descent to visibility for a special purpose.’” Others take the “name” to represent Yahweh’s “power” (NCV) or “authority” (NAB, CEV).

² tn The infinitive absolute here does not add as great an emphasis as normal, but emphasizes the condition that is being set forth (see GKC 342-43 §113.o).
