Zacchaeus was a wealthy tax collector in Jericho who was despised by the Jews due to his profession. He climbed a sycamore tree to see Jesus when he came to town. When Jesus saw Zacchaeus, he called him down and said he would visit his house. After meeting Jesus, Zacchaeus repented of his actions and promised to repay those he had cheated. His encounter with Jesus brought him salvation and changed his life.
