Salam Aleykoum,
John J. Parsons wrote some article dedicated to the hebrew word emet, suggesting that the "Truth" is adressed to a person:
"Indeed, Pilate’s famous question, „What is truth?” is a category mistake, since truth is not about ‘what’ but about ‘Who’."
The text was taken from: http://www.hebrew4christians.com/Glossary/Word_of_the_Week/Archived/Emet/emet.html
also he said in another article:
"The Hebrew word emet has a more concrete meaning than the English word for "truth" (the English word derives from the Greek/Western view of truth as a form of correspondence between language and reality, but invariably languished over epistemological questions that led, ultimately, to skepticism.)"
The text was taken from:

As for the rest what he said about the Mesaiah (Pbuh) we do not necessarily agree.
In the Quran it can be found a following verse which implies that Muhammad (Pbuh) is a personal Truth:
كَيْفَ يَهْدِي اللَّهُ قَوْمًا كَفَرُوا بَعْدَ إِيمَانِهِمْ وَشَهِدُوا أَنَّ الرَّسُولَ حَقٌّ وَجَاءَهُمُ الْبَيِّنَاتُ ۚ وَاللَّهُ لَا يَهْدِي الْقَوْمَ الظَّالِمِينَ
YUSUF ALI TRANSLATION
’’How shall Allah Guide those who reject Faith after they accepted it and bore witness that the Messenger was true and that Clear Signs had come unto them? but Allah guides not a people unjust.’’ (Quran 3:86)
The arabic text of this 'ayah' contains the word "Haqqun" (حَقٌّ) which is synonymous with "al-Haqqu" (الحَقُّ). Now if Amint is indeed an original form of the word "emeth" then even in this way it refers to Muhammad (Pbuh), because Amin was his title by which people know him (the Honest, the Reliable and the Trustworthy). In Qurtubi’s tafsir on sura 2:146 we can find a following hadith:
ورُوِيَ أنّ عمر قال لعبد اللَّه بن سَلاَم: أتعرف محمداً صلى الله عليه وسلم كما تعرف ٱبنك؟ فقال: نعم وأكثر، بعث الله أَمِينه في سمائه إلى أَمِينه في أرضه بنعته فعرفتُه، وٱبني لا أدري ما كان من أُمّه
It was narrated that Omar said to Abdullah bin Salam: "Do you recognize Muhammad (Pbuh) as you recognize your son ?" Yes, and even better ! Allah sent His celestial "Amin" (Gabriel) to His earthly "Amin" (Muhammad/Ahmed) by his attributes (or titles) so I recognized him, as for my son I’m not sure whether he is from his mother.
The Jews believed that "emeth" or 'eh'meth' (actually 'Amint' in original form) is a "Seal of God". Now, we muslims know that the arabic word "Amin" was a unique title of Prophet Muhammad and... also expresses acceptance of our supplication during salat (prayer), and we consciously pronounce it all the time at the end of sura al'Fatiha ! Could this be a "Seal of God" or Seal of God's final message to humanity, the devine message that which - more than 1,400 years ago - brought the "Seal of Prophets" ie. Muhammad (Pbuh)?
