פרשת וישלח
וַיִּשְׁלַח יַעֲקֹב מַלְאָכִים לְפָנָיו אֶל עֵשָׂו אָחִיו אַרְצָה שֵׂעִיר שְׂדֵה אֱדוֹם
וַיִּשְׁלַח יַעֲקֹב מַלְאָכִים לְפָנָיו אֶל עֵשָׂו אָחִיו אַרְצָה שֵׂעִיר שְׂדֵה אֱדוֹם
Parshat Va'yishlach:
And Yaakov sent malachim to Esav his brother, to the land of Seir, the plain of Edom.
The word malachim (the plural of malach) is a curious term. The first instance of the word malach is found in Genesis 16:7. Hagar is met by a malach Hashem. Malach is usually translated as 'angel.' The word can also be used to refer to a human who is an emissary or an agent such as we find in Kings I 19:2:
מלכים א פרק יט
(ב) וַתִּשְׁלַח אִיזֶבֶל מַלְאָךְ אֶל אֵלִיָּהוּ לֵאמֹר כֹּה יַעֲשׂוּן אֱלֹהִים וְכֹה יוֹסִפוּן כִּי כָעֵת מָחָר אָשִׂים אֶת נַפְשְׁךָ כְּנֶפֶשׁ אַחַד מֵהֶם:
(ב) וַתִּשְׁלַח אִיזֶבֶל מַלְאָךְ אֶל אֵלִיָּהוּ לֵאמֹר כֹּה יַעֲשׂוּן אֱלֹהִים וְכֹה יוֹסִפוּן כִּי כָעֵת מָחָר אָשִׂים אֶת נַפְשְׁךָ כְּנֶפֶשׁ אַחַד מֵהֶם:
And Jezebel sent an agent to Elijah saying: Thus will the gods do and thus they will do (even) more, for at this time tomorrow I will place your life as the life of one of them.
I am pretty sure that this latter passage is the first clear instance of the word malach not referring to an angel. I think it is safe to assume that Jezebel was not in command of God's angels!
Every other instance of the word malach in the Torah is clearly referring to an angel of God.
Nonetheless, Rashi here comments that Yaakov sent actual angels to Esav! Rashi's source is the midrash in B'reishit Rabbah where we find two opinions about this matter. One opinion states that Yaakov sent human agents and the other states that he sent actual angels!
Some questions to consider:
1) From the context in the Torah, what indications do we have for each of these opinions?
2) According to the opinion that Yaakov sent actual angels: Why would Yaakov have sent actual angels instead of human agents?
Another thing that has crossed my mind is what is the root meaning of the word malach? Upon consideration, the only other word I can see which is related is מלאכה m'lacha.
The word m'lacha is used first to describe the acts that God did to create the universe. How do you see that word as being related to malach?
