Romans 3:13-14 : Their throat is an open sepulchre; With their tongues they have used deceit: The poison of asps is under their lips. That is a strong figure of speech. From their throats would come words as offensive as the odors from' an open sepulchre. How expressive of the filthiness of their speech! Deceit was one of the sins charged against the Gentiles. Now the Jews are also charged with the same sin. No dependence can be put in what a deceitful person says. Paul also charges that their words were poison like the poison of asps, that their mouth was full of bitterness and cursing. A deceitful person is a liar for gain of some sort, but he expects everyone to believe him; and if you find out that he is a liar, he becomes bitter toward you.
