Whose mouth is full of cursing and bitternesse.
Whose mouth is full of cursing and bitternesse.
Romans 3:12 They haue all gone out of the way: they haue bene made altogether vnprofitable: there is none that doeth good, no not one.
Romans 3:13 Their throte is an open sepulchre: they haue vsed their tongues to deceit: the poyson of aspes is vnder their lippes.
Romans 3:14 Whose mouth is full of cursing and bitternesse.
Romans 3:15 Their feete are swift to shead blood.
Romans 3:16 Destruction and calamity are in their waies,
The verse centers on "whose", "mouth", "full", "cursing", and "bitternesse". It is saying that the verse draws attention to "whose" and "mouth", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 13's "Their throte is an open sepulchre they..." into verse 15's "Their feete are swift to shead blood...", so "whose" and "mouth" belong inside that flow. In Romans context, the local focus is righteousness by faith, union with Christ, life in the Spirit, and God's covenant faithfulness.
A plain takeaway is to answer the verse's own emphasis on "whose" and "mouth" with trust shaped by these words, not by a vague optimism outside the passage.
