New Defender's Study Bible Notes
50:4 tongue of the learned. This passage, especially Isaiah 50:4-9, speaks prophetically of the Messiah as God’s suffering servant, Jesus in His humanity. He spoke words such as no man could speak (Luke 2:40,47; John 7:46; Matthew 7:28-29; 13:54, etc.).
50:5 opened mine ear. The opening of His ear was in reference to the boring of a hole in the ear of a servant willing to remain with his master instead of claiming his freedom (Exodus 21:2-6), symbolic of listening only to the word of his lord (compare John 5:30).
50:6 to the smiters. Fulfilled when Jesus was arrested and brought before the high priest Caiphas (Matthew 26:67; 27:26).
50:7 like a flint. See Luke 9:53. Knowing that He would face death in Jerusalem, Christ nevertheless determined to go, for this was the Father’s will and the only way to save lost sinners.
