my own eyes—I, and not someone else

The synecdoche "my own eyes" represents Job. The phrases "my eyes" and "and not someone else" emphasize that Job himself will actually see God. It is not that someone else will see God and tell Job about him. (See: rc://en/ta/man/jit/figs-synecdoche)

My heart fails within me
