The Bible often talks of people being "troubled." The internal meaning is pretty straightforward; it indicates a state of spiritual turmoil, usually due to the attack of evil desires and false thinking. The Writings do make it clear, though, that in cases when the Lord is the one doing the troubling -- as he does to the Egyptians as the people of Israel are fleeing captivity in Exodus -- it is not because the Lord is using evils and falsities to attack anything. The Lord is perfect love and perfect wisdom, and exists beyond our capacity to conceptualize good, evil, truth and falsity. In essence, "good" is defined as what comes from the Lord, and "truth" is defined as the form that goodness takes. To have evil come from Him, then -- or any idea clothed in a false form -- is a contradiction. So when the Lord is seen "troubling" someone, what they are actually suffering from is their own evil desire and their own false thinking. Evil and falsity wish to attack, and when the Lord deflects them they attack the one who started them in the first place.
