# they will be brought low

"God will bring them low" or "God will destroy them"

# they will be gathered up like all the others

"God will gather them up as he gathered up the other wicked people"

# they will be cut off like the tops of ears of grain

"God will cut them off like a farmer cuts off the top of a stalk of grain". These wicked people will be cut off in the same way heads of grain are cut off during harvest.
