Matthew Poole and continuators on Proverbs 27:14

14 He that blesseth his friend with a loud voice , rising early in the morning , it shall be counted a curse to him .

That saluteth, or praiseth, and applaudeth him to his face, as the manner of flatterers is.

That both he, and others, may be sure to take notice of it.

To perform this Office, to shew his great forwardness, and diligence, and zeal in his service, which was the custom of the Romans afterward, and possibly of some of the Jews at this time.

His friend will value this kind of blessing no more than a curse, because it plainly discovers a base design, and is an high reflection upon him, as if he either did not understand such gross and palpable flattery, or were so ridiculously vainglorious as to be pleased with it.
