13 I bring near my righteousness; it shall not be far off, and my salvation shall not tarry: and I will place salvation in Zion for Israel my glory.
[AD 420] Jerome on Isaiah 46:12-13
(Verses 12, 13.) Hear me, you with hard hearts, who are far from justice. I have brought forth my justice: it shall not be far off, and my salvation shall not delay. I will give salvation in Zion and my glory in Israel. LXX: Hear me, you who have lost heart, who are far from justice. I have brought forth my justice, and the salvation that is from me, I will not delay. I have given salvation in Zion and glory in Israel. To those whom He had spoken before: Hear me, house of Jacob, and all the remnant of the house of Israel. And again: Return, O transgressors, to the heart, even now He calls them by the Hebrew term for unbelief, hardhearted, and according to the Septuagint, those who have lost heart and mind. This was followed by the most learned man and worthy of his name, Stephen the martyr, in his speech to the Jews: With stiff neck and uncircumcised hearts and ears, you always resist the Holy Spirit, just as your fathers did (Acts 7:51). So, they are far from the justice of God because they did not believe in it, which God, in his mercy, made to be near and to come to the lands, not wanting to delay or be far away. For he gave his salvation to Zion and his glory to Israel. Let this be said about the prophecy of the future, and the coming of the Lord and Savior. Moreover, according to history, salvation is given to Zion and glory to Israel; because God has made his justice near, to call from the East a bird and from a far land a man of his will, who would avenge the injustices of Israel and the destroyed Jerusalem, and would destroy the Medes and Persians, and the Babylonians and the Chaldeans, as the following words of the Prophet testify.

[AD 528] Procopius of Gaza on Isaiah 46:13
For God did not hate those whom he took out of Israel but intended salvation for them, just like the cutting and draining done by doctors. For all punishment was carried out for their advantage. He adds to the underlying form of the particular its significance for the human race. For the salvation through Cyrus is particular. That through Christ is universal. “I will not delay” is similar to “a little time it will come and will not delay.” “Zion” we take to be the church, in which we receive his salvation in glory, thus being complete in the spiritual Israel; that is, we gain a mind that, seeing God, fulfills us as children according to the promises of Abraham.
