But they were startled and terrified, thinking ¹  they saw a ghost. ² 

When they saw him walking on the water ¹  they thought he was a ghost. They ²  cried out,

When ¹  the disciples saw him walking on the water ²  they were terrified and said, “It’s a ghost!” and cried out with fear.

Look at my hands and my feet; it’s me! ¹  Touch me and see; a ghost ²  does not have flesh and bones like you see I have.”
