Targum zu Bereschit 32:27

And he said, Let me go, for the column of the morning ascendeth; and the hour cometh when the angels on high offer praise to the Lord of the world: and I am one of the angels of praise, but from the day that the world was created my time to praise hath not come until now. And he said, I will not let thee go, until thou bless me.

And he said, Send me away, for the column of the dawn ariseth, and, behold, the hour cometh for the angels to praise. And he said, I will not release thee until thou bless me.
