Darby

5 And entering into the sepulchre, they saw a young man sitting on the right, clothed in a white robe, and they were amazed and alarmed^D7147;

Darby Bible Notes

alarmed - The Greek word embraces, I think, the complex idea expressed by both 'amazed' and 'alarmed.' The second time it is used I have given the latter only, as sufficiently recalling the idea. The word occurs only here and in chs. 9.15; 14.33.

KJV

5 And entering into the sepulchre, they saw a young man sitting on the right side, clothed in a long white garment; and they were affrighted.
