Isaiah 50:6 - Matthew Poole's English Annotations on the Holy Bible

I gave my back to the smiters; I patiently yielded up myself, and turned my back to those who smote me. I was willing not only to do, but to suffer, the will of God, and the injuries of men. This and the following passages were literally fulfilled in Christ, as is expressly affirmed, Matthew 26:57,67 Matthew 27:26,30, and elsewhere; but we read of no such thing concerning Isaiah. And therefore it is most safe and reasonable to understand it of Christ; the rather, because it is not usual with the prophets to commend themselves so highly as the prophet here commends the person of whom he speaketh. Plucked off the hair; which was a contumely or punishment inflicted upon malefactors, Nehemiah 13:25. I hid not my face from shame, from all manner of reproachful usages; but did knowingly and willingly submit myself there unto. And spitting: spitting in a man's face was used in token of contempt and detestation, Numbers 12:14 Job 30:10; and this was literally fulfilled in Christ, Matthew 26:67.
