Musar do Rodzaju 24:61

In 24,61 we read about Rebeccah and her maidservants: ותרכבנה על הגמלים ותלכנה אחרי האיש, ויקח העבד את רבקה וילך . "They rode on the camels and followed the man; the servant took Rebeccah and went (on his way). Clearly, the reason that we find two descriptions of Eliezer in one verse is that Mattaron the heavenly messenger was present until the mission had been concluded. The mission was not concluded until Eliezer was out of Charan on his way back. This process is indicated by the words in 24,61 ותקם רבקה ונערותיה ותלכנה אחרי האיש. Immediately after that, when Mattatron returned to Heaven, the Torah reverts to describing the man leading Rebeccah as עבד. It is possible that the word וילך, he went on his way, refers to Mattaron who returned to the Celestial Regions he had come from.
