Romanos 3:14

Whose mouth is full of cursing and bitterness.

Paul was continuing to pile up scriptures to prove the wickedness of that generation which rejected Christ. This verse is a paraphrase of Psalms 10:7; and, like the three charges listed in Romans 3:13, deals with sins of the tongue. The fact that this class of sins is mentioned at such length in this context shows how important the tongue is as an indicator of character.
