Mark 9:30-37
³⁰Jesus and the disciples went on from there 
     and passed through Galilee. 
          Jesus did not want anyone to know it;
               ³¹for he was teaching his disciples, saying to them, 
                    “The Human One is to be betrayed into human hands, 
                    and they will kill him, 
                    and three days after being killed, 
                         he will rise again.”
                    ³²But they did not understand what he was saying 
                         and were afraid to ask him.

³³Then they came to Capernaum; 
     and when Jesus was in the house he asked them, 
          “What were you arguing about on the way?”
     ³⁴But they were silent, 
          for on the way they had argued with one another who was the greatest. 
³⁵Jesus sat down, 
     called the twelve, 
     and said to them, 
          “Whoever wants to be first must be last of all and servant of all.”  
³⁶Then he took a little child 
     and put it among them; 
     and taking it in his arms, 
          he said to them,
               ³⁷“Whoever welcomes one such child in my name welcomes me, 
                    and whoever welcomes me welcomes not me 
                         but the one who sent me.”

Queeries for the text:
Where were they coming from?
Why were they afraid to ask?
How long will it take the disciples to get it?
Who were arguing?
How do humans try to be the greatest?
If we're just trying to be last in order to be first, does it really count?
From whom did Jesus get the child?
How do we welcome the children in Jesus' name?
