Commentaire sur La Genèse 24:40

ישלח מלאכו, I know they will give you their daughter.

ישלח מלאכו, “He will send His angel, etc.” Avraham had been referring to a specific angel, as in כי ילך מלאכי לפניך, “for My angel will travel in front of you” (Exodus 23,23) [where G’d speaks of an angel that will represent Him specifically during the conquest of the land of Canaan. Ed.] He did not refer to the angel described in Exodus 33,2 ושלחתי לפניך מלאך, “I will send an angel ahead of you.” [In that instance G’d’s benevolent providence had been reduced to a more indirect level, as evidenced by the absence of the suffix ו, “His” at the end of the word מלאך. Here the word מלאכו appears twice, indicating that there were two angels active to ensure the success of Eliezer’s mission. (compare 24,7) The first angel’s mission was to keep harm from befalling Eliezer and his men; the second angel was to ensure the arrival of the right girl at the right place at the right time.
