Psalm 10.7
Septuagint

ou araV to stoma autou gemei kai pikriaV 
kai dolou, upo thn glwssan autou kopoV kai ponoV
New Testament - Romans 3.14

wn to stoma araV kai pikriaV gemei
 
Septuagint

Whose mouth is full of cursing and bitterness, and fraud:  under his tongue are trouble and pain
New Testament

Whose mouth is full of cursing and bitterness
Masoretic Text

His mouth is full of cursing and deceit and oppression:  under his tongue is mischief and iniquity
Comments:  The MT omits the mention of “bitterness” using “deceit” instead.  The NIV has “lies” instead of  “deceit.”  The NT and the LXX are in agreement, though there are small differences in construction.
