וַיִּרְחַ֥ץ פָּנָ֖יו וַיֵּצֵ֑א וַיִּ֨תְאַפַּ֔ק וַיֹּ֖אמֶר שִׂ֥ימוּ לָֽחֶם׃
At hinugasan niya ang kanyang mukha, at lumabas siya; at pinigil niya ang kanyang sarili, at sinabi niya: “Maghain kayo ng pagkain.”
Rashi
ויתאפק AND HE REFRAINED HIMSELF — He made a strong effort. The root in this sense occurs in (Job 41:7) אפיקי “the strong parts of the shields”. Similar also is (Job 12:21) “And He looseth the belt of the (אפיקים) strong”.
Radak
וירחץ...ויתאפק; he managed to gain control of himself and to stop himself from weeping anymore.
Chizkuni
וירחץ פניו, “he washed his face;” seeing that he had to sit with them and to stand up after the meal, and they would otherwise see that he had been crying, unless he washed his face immediately. But earlier, in 42,24, where he did not have to face his brothers except very briefly, he did not feel the need to wash his face.
