Scrupulous Reserve

In his book Principles of Conduct: Aspects of Biblical Ethics John Murray writes about the reserve required of a truthful person:

No warning or plea is more germane to the question of truth than that we cultivate the reserve and exercise the caution whereby we shall be preserved from rash and precipitate judgments and from the vice of peddling reports that are not authenticated by the proper evidence… The man of truth is the man of resolute, decisive conviction; he is also the man of scrupulous reserve. “Thou shalt not go up and down as a talebearer among thy people” (Leviticus 19:16)
