Why did David still call Saul “the Lord’s anointed” (1 Samuel 26:9)?
Saul’s royal office carried with it divine sanction by virtue of his anointing. The designation “the Lord’s anointed” is used interchangeably in the books of Samuel for “the king” (see 1 Samuel 2:10). David, no doubt, used “the Lord’s anointed” in this fashion, maintaining his high regard for the office, in spite of the man who held it.
