“I gave My back to the smiters, and My cheeks to them that plucked off the hair: I hid not My face from shame and spitting.” Isaiah 50:6 (KJB)
This is a prophecy of the trial, pain, beating, the suffering of the sinless Son of God as He gave Himself as the propitiation for our sins. A prophecy given to the prophet Isaiah around 700 years before Jesus was even born in the manger.
From Jamieson, Fausset, and Brown Commentary on verse six…
“smiters — with scourges and with the open hand (Isa_52:14; Mar_14:65). Literally fulfilled (Mat_27:26; Mat_26:27; Luk_18:33). To “pluck the hair” is the highest insult that can be offered an Oriental (2Sa_10:4; Lam_3:30). “I gave” implies the voluntary nature of His sufferings; His example corresponds to His precept (Mat_5:39).
spitting — To spit in another’s presence is an insult in the East, much more on one; most of all in the face (Job_30:10; Mat_27:30; Luk_18:32).” From the Jamieson, Fausset, and Brown Commentary
O, come to Jesus Christ who loved us so much He gave Himself to redeem us to the Father God in Glory.
