I have trodden the winepress alone; and of the people there was none with me: for I will tread them in mine anger, and trample them in my fury; and their blood shall be sprinkled upon my garments, and I will stain all my raiment. And of the people there was none with me - I was wholly abandoned by them: but a good meaning is, No man has had any part in making the atonement; it is entirely the work of the Messiah alone. No created being could have any part in a sacrifice that was to be of infinite merit.
And I will stain "And I have stained" - For אגאלתי egalti, a verb of very irregular formation, compounded, as they say, of the two forms of the preterite and future, a MS. has אגאלהו egalehu, the regular future with a pleonastic pronoun added to it, according to the Hebrew idiom: "And all my raiment, I have stained it."
