Keluaran 23:21

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.

Mazmur 107:17

107:17 They acted like fools in their rebellious ways, ² 

and suffered because of their sins.

[23:21]  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).

[107:17]  ² tn Heb “fools [they were] because of the way of their rebellion.”
