Do you have a brother ?

?   חַי֙ הֲיֵ֣שׁ לָכֶ֣ם אָ֔ח

" Do you have a brother?'" (43:7).

The final letters of the words chai ha-yeish lachem ach ("...alive do you have a brother") are yud, shin, mem, and ches. These letters spell the word "Moshiach" (משיח). Furthermore, the word lachem (לכם) can be rearranged to spell melech (מלך), "king." This verse is an allusion to Melech ha-Moshiach, who will come lachem, "for you," the Jewish people.
