Deuteronomy 25.4
Septuagint

New Testament - 1 Corinthians 9.9

ou khmwseiV boun alownta

1 Timothy 5.18

boun alownta ou fimwseiV
Septuagint

Thou shalt not muzzle the ox that treads out the corn
 
New Testament

1 Corinthians 9.9:  Thou shalt not muzzle the ox when he treadeth out the corn

1 Timothy 5.18:  Thou shalt not muzzle the ox when he treadeth out the corn
Masoretic Text

Thou shalt not muzzle the ox when he treadeth out the grain
Comments:  The NT, LXX and MT agree.  Several NT manuscripts (including P46 and Codices S and A) have fimwseiV for khmwseiV in 1 Cor 9.9, making the agreement there perfect.
