But Israel shall be saved in the LORD with an everlasting salvation: ye shall not be ashamed nor confounded world without end.
(But) Israel shall be saved in the Lord (Isaiah 45:24-25) - contrasted with the idols which cannot give even temporary help (Isaiah 45:16).
With an everlasting salvation. In Yahweh there is everlasting salvation (Isaiah 26:4).
Ye shall not be ashamed - opposed to the doom of the idolaters, who, in the hour of need, shall be "ashamed" (note, Isaiah 45:16).
