Jamieson, Fausset and Brown on Matthew 12:20

20. A bruised reed shall he not break, and smoking flax shall he not quench, till he send forth judgment unto victory--"unto truth," says the Hebrew original, and the Septuagint also. But our Evangelist merely seizes the spirit, instead of the letter of the prediction in this point. The grandeur and completeness of Messiah's victories would prove, it seems, not more wonderful than the unobtrusive noiselessness with which they were to be achieved. And whereas one rough touch will break a bruised reed, and quench the flickering, smoking flax, His it should be, with matchless tenderness, love, and skill, to lift up the meek, to strengthen the weak hands and confirm the feeble knees, to comfort all that mourn, to say to them that are of a fearful heart, Be strong, fear not.
