Some fifteen hundred years after the first Passover[1],
thirteen Jewish men ate a Passover meal in the city of Jerusalem. This
was the "Last Supper[2]," eaten by Jesus Christ and his twelve
disciples, his closest followers.
Many special words and phrases referring to this and other related
events have become part of the English language. For example, someone's
"last supper" can mean a final activity before a dangerous action, or
even before death.
One of the closest companions of Jesus, who ate this last Passover
supper, was named Judas. However, two days before eating the Passover
with Jesus, Judas agreed to help the Jewish religious and political officials
capture Jesus, betraying him. And so, anyone who betrays[3] (turns
against) a friend is now called "a Judas".
Two of the disciples prepared the Passover meal in a borrowed
room, called an " upper room," a room upstairs. Now "an upper room" means
a quiet place to be with God Jesus and his disciples, all of them believing
Jews, came to the upper room to observe the Passover on Thursday, the
day before what is now called Good Friday.
Before beginning the meal, Jesus took a basin of water, and washed
the dust from the feet of each of his disciples, the work of a household
servant. Jesus explained that he was showing the Twelve that he, their
teacher and leader, was also their servant. So in English now, "to wash
someone's feet " means to lovingly help or serve someone who is socially
lower than you.
