Judah is referring to Benjamin, Rachel's last born before she died.
## You will not see my face ##
Judah uses this phrase twice in 43:3-5 to emphasize to his father that they cannot return to Egypt without Benjamin. The phrase "my face" refers to the man, who is Joseph. Alternate translation: "You will not see me." (See: [[rc://en/ta/man/translate/figs-synecdoche]])
