his eyes were dim

This speaks about being nearly blind as if the eyes were a lamp and the light has nearly gone out. Alternate translation: "he was nearly blind" or "he was almost blind" (See: rc://en/ta/man/jit/figs-metaphor)

Here I am

"I am here" or "I am listening." See how you translated this in Genesis 22:1.
