And there shall be fear and great trembling upon the earth means everyone on earth will tremble with fear because of the war.

And those who see that wrath shall be horror-stricken, and they shall be seized with trembling: This sentence repeats the ideas in the previous one for emphasis. Good News Bible combines the two sentences, but if possible, it is better to keep both. That wrath refers to the war and violence. This sentence may be rendered “People who actually see this horrible sight [or, event] will be filled with horror and shake uncontrollably.”

An alternative model for this verse is:

• People all over the earth will tremble with fear. Those who actually see this terrible thing [or, horror] will be filled with horror and shake uncontrollably.
