THE EPISTLE TO THE ROMANS - Chapter 3 - Verse 14
Verse 14. Whose mouth. Ps 10:7. The apostle has not quoted this literally, but has given the sense. David in the psalm is describing his bitter enemies.
Cursing. Reproachful and opprobrious language, such as Shimei used in relation to David, 2 Sa 16:5,7,8.
Bitterness. In the psalm, deceits. The word bitterness is used to denote severity, harshness, cruelty; reproachful and malicious words.
{u} "whose mouth is full" Ps 10:7
