New Defender's Study Bible Notes
3:12 not make him known. These unclean spirits recognized Christ, even though His own friends thought He was mentally ill (Mark 3:21). Nevertheless, He did not want the spirits to identify Him openly. The Lord Jesus does not need nor desire any affirmation by His enemies, but only the witness of His own disciples. There is always a great temptation for Christians to seek acclaim or testimony from ungodly people of influence, but Christ Himself would have none of it.
