The current quote is from the Sanhedrin tractate, and appears only in the Hebrew language (in two different fonts). The treatise is in the Nezikin order out of the Mishnah. The full sentence is: Therefore, a single person was created in the world, to teach that anyone who loses one soul, is exalted over him as if he had lost an entire world; And everyone who sustains one soul is exalted over him as if a whole world existed (Version without mention of Israel)
Rambam gave it a more universal validity in his quote "Whoever sustains one soul in the world" Translation of the text on the sign
Anyone who sustains one soul from Israel
The Scripture indicates
As if there were a whole world
