Demetrius

by the truth itself

"the truth itself speaks well of him." Here "truth" is described as a person speaking. Alternate translation: "everyone who knows the truth knows he is a good person" (See: rc://en/ta/man/jit/figs-personification and rc://en/ta/man/jit/figs-explicit and rc://en/ta/man/jit/figs-rpronouns)
