Isaiah 63:5

(Verse 3 and following) I have trodden the winepress alone, and of the peoples there was no man with me. I have trodden them in my anger, and trampled them in my fury: and their blood has stained my garments, and all my clothing is polluted. For the day of vengeance is in my heart, and the year of my redemption has come. I looked around, and there was no helper: I sought, and there was no one to assist. So my own arm brought salvation to me, and my own wrath supported me. And I have trampled upon the peoples in my anger, and I have made them drunk in my indignation, and I have brought down their strength to the earth. Seventy times because of what we said, I alone have trampled the winepress, they have interpreted, a full trampling, which is more to be read with the previous chapter than as the beginning of the following one. The rest they have translated thus. And there is no one among the nations with me, and I have trampled upon them in my anger, and I have crushed them like the ground, and I have poured out their blood upon the earth, and I have defiled all my garments. For the day of vengeance is in my heart, and the year of my redemption has come. I looked, but there was no one to help; I was appalled, but there was no one to uphold; so my own arm brought me salvation, and my wrath upheld me. I trampled down the peoples in my anger; I made them drunk in my wrath, and I poured out their lifeblood on the earth. For the press is called Geth in Hebrew, as Theodotion has translated the Hebrew word in Greek. But Symmachus, whom we also follow, renders it better in this place. For the word Phura is ambiguous, and usually signifies both a winepress and a jug. It must be said, therefore, about the winepress, that according to the custom of Holy Scripture, sometimes it is used for vengeance and punishments of sins, sometimes for the gathering of new fruits. […]

Second, he sets out the necessity of salvation: I looked about, and there was none to help, the human race, who could save it, above: he saw that there is not a man (Isa 59:16); or there was none to help, me on the cross: …

None to help - Not that he needed it, but to see what men would do, in regard his people needed it; therefore the standing, or not standing by his people, is the same thing with standing, or not standing by him. Uphold - A metaphor, taken from a staff, that is an help to one that leans on it.

But this is most fully applicable to Christ's victories over our spiritual enemies, which he obtained by a single combat. He trod the wine-press of his Father's wrath alone, and triumphed over principalities and powers in himself, Col. ii. Of the people there was none with him; for, when he entered the lists with the powers of darkness, all his disciples forsook him and fled.

God wrought salvation for the oppressed Jews purely because he was very angry with the oppressing Babylonians, angry at their idolatries and sorceries, their pride and cruelty, and the injuries they did to his people, and, as they increased their abominations and grew more insolent and outrageous, his anger increased to fury.
