This powerful phrase is often used to defend certain preachers from criticism or to claim that believers are promised protection from all harm. But is that what the scripture really means, or is this a case of bad theology ignoring the context? What does the Bible truly mean when it says, “Do not touch my anointed ones” (1 Chronicles 16:22, ESV)? We examine the original command given concerning the patriarchs—Abraham, Isaac, and Jacob—to see why God rebuked kings for their sake. Find out who "God's anointed" truly are, why David refused to harm King Saul (1 Samuel 26:9–11), and what this means for all believers today, who are also anointed (2 Corinthians 1:21–22), as we trust God's ultimate plan (Philippians 1:6).
