The Robbers are a group of nameless thieves that appeared in Jesus' parable The Good Samaritan. The Parable could be read in Luke 10: 29-37.
The Good Samaritan
The story begins with a certain man (who may or may not be Jewish depending on the version) heading from Jerusalem towards Jericho. While he's on the road to Jericho, he's attacked by a group of thieves who beat him, stripped him of his clothes, and robbed him dry. They then leave him on the road half dead.
A priest comes by and sees the bruised man. However, he kept walking. A Levite comes to the area later on and sees the helpless man and he too ignores him and continues on his way. Suddenly, a Samaritan happened to have been coming by, and he takes pity on the man. He binds up the man's wounds, and he then poured oil and wine over them. He later took the injured man to an inn. He then promised to pay the innkeeper back for his service with the injured man.
Jesus then asked the lawyer who was pondering about who qualified as his neighbor which of the three men was a neighbor towards the injured man. The lawyer replied that the Samaritan was, and Jesus told him to do the same onto all people.
