Charles Ellicott Commentary Genesis 43:34

"And he took [and sent] messes unto them from before him: but Benjamin`s mess was five times so much as any of theirs. And they drank, and were merry with him." — Genesis 43:34 (ASV)

Messes. —A portion of food from that prepared for the chief is regarded in the East as a mark both of honor and friendship, and the largeness of Benjamin’s mess marked him out as the special object of Joseph’s regard. The words literally are, “And the portion of Benjamin was great above the portions of all of them fi ve hands,” that is, five times. It has been supposed that Joseph intended to try his brothers by this preference, and see if they were still envious. More probably it was dictated simply by his love.

They drank and were merry with him. —Heb., They drank and were drunken with him. The verb is that used of Noah in Genesis 9:21, but probably the rendering in Haggai 1:6, and were filled with drink, would give the right meaning. They lost all fear and suspicion, and gave themselves up to enjoyment.
