John 13.28-30 cont.
28 Yet none of those who were reclining at the table knew what He said to him.
29 For some thought, since Judas had the money bag, Jesus told him to buy what we needed for the feast, or so that He could give something to the poor.
30 Then having taken the piece of bread he went out, and it was night.
When driving a vehicle it is vital to be constantly observant. Drivers need to be aware of what is happening around them, they need to try and anticipate the actions of all other road users. The drivers’ powers of observation will help them to plan ahead and to avoid emergency situations.
It would appear as though either the disciples were not observant about what was going on between Jesus and Judas, or they were unable to observe it.
They obviously knew that Jesus had sent Judas out, but they did not realize that his being sent out by Jesus had anything to do with the betrayal that He had spoken about.
None of them jumped to the conclusion that Judas was the betrayer, even though he was known to divert their funds to his own personal desire.
How quick are we to make assumptions about people? Perhaps all too often we jump to a conclusion about somebody, based on their reputation. It is interesting that the eleven disciples did not do this. No doubt their experience of being with Jesus for three years had taught them not to judge one another.
Jesus had taught them this as part of what we call the ‘Sermon on the Mount’:
 “Stop judging others, and you will not be judged.  For others will treat you as you treat them. Whatever measure you use in judging others, it will be used to measure how you are judged” – Matthew 7.1-2 (NLT).
In the light of this let us be quick to assume the best and slow to assume the worst in people.
Maybe this was the reason that they assumed that Judas had been dispatched by Jesus to go and buy provisions for the Passover.
W Barclay gives us an insight as to why they might have thought this. It was customary for people to try and meet the needs of the poor, especially at the Passover time. People who had the means to do so would buy extra provisions so that they could give it to the poor, enabling them to also join in the festivities of the Passover Meal.
This is something that has been carried forward into the life of the church. We see it today in many forms, especially in regards to churches running food banks.
