What do "truth" and "justice" translate to in Hebrew (phonetically)...
...as Shimon ben Gamliel used them in his quote, "By three things the world is sustained: Truth, Justice, and Peace." Under Truth, Justice, and Peace in the plaque I've gotten, it has the Hebrew characters, but I can't remember how they're pronounced. (I know that Peace is Shalom; that's an easy one.) :)

Question

Answer

Justice is צדק (tsedek)
Truth is אמת( emet)
But if you want to hear the real pronunciation, check it out in the Google translate or get in touch with native Hebrew speaker.
