In the context of the Pharisees' strict separation from those deemed unclean, Simon, the Tanner, exemplifies a profession they avoided due to its inherent impurity. Tanning involved constant contact with dead animal skins, rendering the tanner perpetually unclean in the eyes of the Pharisees. Thus, they would shun such a person to prevent defilement, as seen in the case of Peter visiting a tanner in Joppa. This avoidance underscores the Pharisees' rigid adherence to laws of purity, prioritizing ritual cleanliness over association with those engaged in base occupations.

Toward the end of chapter 9, Peter is brought back into the narrative, located in the area of Lydda and then Joppa on the Mediterranean Sea. It was in Joppa that he stayed with a man named Simon, a tanner. According to Jewish regulations of the time, a tanner was considered unclean due to the nature of his work, involving contact with materials often derived from unclean animals. Despite this, Peter, a Jew familiar with the strictures of Judaism, appears to be shedding some of his scruples about such matters, recognizing they were not rooted in biblical injunctions but in cultural traditions. This shift in perspective is significant as it prepares him for the events that unfold in chapter 10. In chapter 10, Cornelius, a Roman centurion in Caesarea, receives a vision from an angel of God instructing him to send for Simon, whose surname is Peter, lodging with Simon, a tanner, by the sea in Joppa. The angel assures Cornelius that Peter will tell him what he must do. Following this divine instruction, Cornelius sends two household servants and a devout soldier to Joppa to fetch Peter from the house of Simon, the tanner. As these men approach, Peter, deep in thought after his own vision, is directed by the Spirit to go with them, confirming that they were sent by divine purpose from the house of Simon, the tanner. Later, in chapter 11, Peter recounts these events to the apostles and brethren in Judea, explaining how the Spirit led him from the house of Simon, the tanner, in Joppa to Cornelius in Caesarea. He details the vision and the arrival of the men sent by Cornelius, emphasizing that his stay with Simon, the tanner, was the starting point of this significant journey that ultimately led to the acceptance of Gentiles into the church.

In the unfolding narrative of the early church's expansion, Peter, after performing a remarkable miracle in Joppa, stayed many days with Simon, a tanner. This choice was significant, as according to the Jewish regulations of that time, a tanner was considered unclean due to the processes involved in softening hides for clothing and shoes. Peter's decision to reside with Simon suggests a shift in perspective, as there is no indication that he hesitated or gave a second thought to the potential ceremonial uncleanness resulting from this close contact. This act subtly reflects a broadening understanding within the church regarding certain traditional regulations attached to the law of God, marking a step toward greater inclusivity as the gospel began to reach beyond its initial boundaries.
