New Testament - 1 Corinthians 14.21

en eteroglwssoiV kai en ceilesin eterwn
lalhsw tw law toutw 
kai oud outwV eisakousontai mou, legei kurioV
 

Septuagint

by means of the contemptuous wordsof the lips, by means of another language:  for they shall speak to this people saying to them, This is the rest to him that is hungry, and this is the calamity:  but they would not hear

New Testament

By men of strange tongues and by the lips of strangers will I speak unto this people; and not even thus will they hear me, saith the Lord

Masoretic Text

Nay, but by men of strange lips and with another tongue will he speak to this people; to whom he said, This is the rest, give ye rest to him that is weary; and this is the refreshing:  yet they would not hear

Comments:  The NT, LXX and MT agree.  The quotation is very loose.
