וּלְבַ֥ב נִמְהָרִ֖ים יָבִ֣ין לָדָ֑עַת וּלְשׁ֣וֹן עִלְּגִ֔ים תְּמַהֵ֖ר לְדַבֵּ֥ר צָחֽוֹת׃
Hati orang-orang yang gegabah akan mengerti untuk mengetahui, dan lidah orang-orang yang gagap akan segera berbicara dengan jelas.
Shenei Luchot HaBerit
It is even possible to understand the word מלאכים as the very merits which Jacob had accumulated. He "sent" these ahead of him to impress any would-be accuser in the Heavenly Regions. We have a tradition that every good deed in this world creates an angel, whereas every sin creates a destructive force. This idea is expressed in Isaiah 58,8: והלך לפניך צדקך, "Your righteousness will walk ahead of you." The word "in front of him" in 32, 4, may well allude to this, seeing that the word is apparently redundant. It would have been enough for the Torah to write: "Jacob sent messengers to Esau."
