Sure, here's a summary of Zacchaeus' story. The story of Zacchaeus is found in the New Testament of the Bible, in the Gospel of Luke, Chapter 19, verses 1-10.

Zacchaeus, a wealthy tax collector, wanted to see Jesus as he passed through Jericho. Since he was small, he climbed a sycamore-fig tree. When Jesus reached the tree, he told Zacchaeus to come down because he would be a guest in his house. This surprised and angered the crowd, as tax collectors were often unpopular. However, Zacchaeus promised to give half of his possessions to the poor and to pay back four times as much to anyone he had defrauded.

Jesus acknowledged Zacchaeus' repentance and explained that salvation had come to his house that day, emphasizing that the Son of Man had come to seek and save the lost. This story explores the themes of repentance, generosity, and the transformative power of encountering Jesus.

I think this was not just about repentance and reparation, but also about finding and harnessing dead, i.e. useless, capital and converting it into capital for the benefit of people.
