Στέλλω in the middle voice (στέλλομαι) means to draw back from, avoid, withdraw from, or shun. Paul uses this verb twice to command avoidance of certain people or behaviors. In 2 Corinthians 8:20, Paul is careful to avoid any accusation of mishandling the financial collection, so he sends multiple trustworthy people with it. In 2 Thessalonians 3:6, Paul commands believers to withdraw from brothers living in idleness and not according to apostolic tradition. The verb suggests deliberate distancing, not violent expulsion but strategic separation to maintain purity and avoid harm or scandal.
