וַיֹּ֣אמֶר שַׁלְּחֵ֔נִי כִּ֥י עָלָ֖ה הַשָּׁ֑חַר וַיֹּ֙אמֶר֙ לֹ֣א אֲשַֽׁלֵּחֲךָ֔ כִּ֖י אִם־בֵּרַכְתָּֽנִי׃
И сказал он: 'Отпусти меня, потому что день наступит.' И сказал он: 'Я не отпущу тебя, если не благословишь меня.'
Rashi
כי עלה השחר FOR THE DAY BREAKETH, and I have to sing God’s praise at day (Chullin 91b; Genesis Rabbah 78:1).
Chizkuni
שלחני כי עלה השחר, “give me permission to leave for dawn has arisen!” “Until now I held you up from proceeding according to plan; now you have permission to proceed on your way.” An alternate exegesis of this strange conversation: The angel told Yaakov that since it now was almost daylight, he no longer had anything to fear from him. It is not customary for destructive forces to do their jobs during the daylight hours.
