Proverbs 11:13

A talebearer revealeth secrets: but he that is of a faithful spirit concealeth the matter.

A talebearer [Hebrew, one walking as a detractor, raakiyl (H7400 )] revealeth secrets. The association of the verb walking with detractor, literally, a merchant, is due to the fact that the detractor goes about like a trafficker, carrying the wares of scandal, gathered from various quarters, and circulating them far and wide (Jeremiah 6:28, "Walking with slanders;" Leviticus 19:16. "Thou shalt not go up and down as a talebearer among thy people;" 1 Peter 2:1; James 4:11). In this case it aggravates the offence that what the talebearer circulates was a 'secret' committed to him in confidence.

But he that is of a faithful spirit concealeth the matter - answering to "a man of understanding holdeth his peace" (Proverbs 11:12). "He that is of a faithful spirit" - opposed to "a talebearer;" one "faithful" to his premise of secrecy given to his friend.
