A disembodied spirit, supposedly residing in sheol (Job 26: 5; Isa. 14: 9) and capable of being brought up by a professional medium (1 Sam. 28: 12–14). The disciples mistake Jesus walking on the sea for a ghost (Mark 6: 49) as they also do when they see him in his risen form after Easter (Luke 24: 37).

The ‘Holy Ghost’ (Luke 1: 15, AV) is now generally rendered ‘Holy Spirit’ in modern versions on account of the former term being obsolete.
