The Mekhilta DeRabbi Yishmael offered a remarkable tradition about Joshua the son of Nun and his unique relationship with the manna. (Psalms 78:25) says "He sent them sustenance to satiety," and the rabbis interpreted "them" not as a reference to all of Israel but specifically to Joshua, Moses' servant and eventual successor.
According to this reading, the manna descended for Joshua "over and against all of Israel," meaning his portion was distinct from and perhaps greater than what the rest of the nation received. Joshua occupied a special status in the wilderness. He never left the Tent of Meeting (Exodus 33:11). He was Moses' closest disciple and the future conqueror of the Promised Land. The manna honored that status by singling him out.
An alternative opinion pushed the idea even further. "Others say" that the manna descended directly onto Joshua's limbs. It did not fall to the ground for him to collect like everyone else. Instead, it landed on his body, and from his own limbs he took it to eat. The bread of heaven attached itself to Joshua personally, as though his body was the designated landing surface for God's provision.
The rabbis connected this to (Numbers 27:18), where God calls Joshua an "ish," a man of distinction. The verse in Psalms says "the bread of abirim was eaten by ish," by the man, singular. This is Joshua. While all of Israel ate the manna collectively, Joshua ate it in a way that marked him as unique among the people, his body itself serving as the table on which God laid the bread from heaven.
