'Ghost' in the Bible

"This is what the Lord GOD says: "When I turn your city into a ghost town, when I flood you with deep water that covers you completely,

I'm going to turn your cities into ghost towns, and you will become a ruin. Then you will learn that I am the LORD.

When the disciples saw him walking on the sea, they were terrified and cried out, "It's a ghost!" And they screamed in terror.

but when they saw him walking on the sea, they thought it was a ghost and began to scream.

They were startled and terrified, thinking they were seeing a ghost.

Look at my hands and my feet, because it's really me. Touch me and look at me, because a ghost doesn't have flesh and bones as you see that I have."
