General Information:

Isaiah is speaking to the people of Judah.

Strengthen the weak hands, and make steady the knees that shake.

The words "weak hands" and "knees that shake" represent a person who is fearful. Alternate translation: "Strengthen those whose hands are weak and whose knees shake from fear" (See: rc://en/ta/man/jit/figs-synecdoche)
