"I waited to hear what you would say." The word "your" refers to Job's friends and so is plural. (See: [[rc://en/ta/man/jit/figs-you]])
# searching for a word
The word "word" is a synecdoche for an entire message, and "searching for" a word as if it were a solid object is a metaphor for thinking of the right thing to say. Alternate translation: "thinking about what to say" or "trying to think of the right thing to say" (See: [[rc://en/ta/man/jit/figs-synecdoche]] and [[rc://en/ta/man/jit/figs-metaphor]])
