Translation
The locusts
were told they could not harm
the grass of the earth, any green thing or any tree,
but only the men
who do not have
the seal of GOD on their foreheads.
Paraphrase
These agents of destruction were told they could not destroy man’s food supplies, rather they were only allowed to directly harm those men who do not have the demonstration of acceptance, approval and protection by THE CREATOR AND OWNER OF ALL THINGS constantly in their focus as a top priority.
