'Tax Collector' in the Bible

As he was walking along, he saw Levi, the son of Alphaeus, sitting at the tax collector's desk. Jesus told him, "Follow me!" So Levi got up and followed him.

And it happened that Jesus was reclining at the table in Levi’s house, and many tax collectors and sinners [including non-observant Jews] were eating with Him and His disciples; for there were many of them and they were following Him.

When the scribes [belonging to the sect] of the Pharisees saw that Jesus was eating with the sinners [including non-observant Jews] and tax collectors, they asked His disciples, “Why does He eat and drink with tax collectors and sinners?”
