So then, my brothers and sisters, when you come together to eat, wait for one another. If you are hungry, eat at home, so that when you come together, it will not be for your condemnation. About the other things I will give instructions when I come. (1Corinthians 11: 33-34)

The Greek ekdechomai is translated above as wait. It can also mean "receive from."

In the church of my childhood the bread and fruit of the vine are passed from neighbor to neighbor. The deacons bring the sacraments into the congregation where, like a family style meal, they are shared as "living symbols of body and blood of Jesus."

To receive from often involves waiting. But ekdechomai also means to expect. We are to wait expectantly.
