Augustine of Hippo
What is this? Let him delve into these texts, no longer as a Manichaean, but rather as a Jew, and let him determine whether God declared about any angel, "My name is in him" (Ex. 23:21), except for the one promised as a leader to the land of promise. Next, let him investigate among the followers of Moses to find who would guide the people, ultimately discovering Jesus, known by that name not from the start but after a change of designation. For the one who proclaimed, "My name is in this Jesus," is indeed the true Jesus, the Sovereign and Guide of the people toward the inheritance of everlasting life, as established by the New Covenant, whose archetype was the Old Covenant. Therefore, nothing could be more prophetic than what has been declared.
