“And it came to pass, when the time was come that he should be received up, he stedfastly set his face to go to Jerusalem,”
King James Version (KJV)
9:51 The days are fulfilled that he should be received up - That is, the time of his passion was now at hand. St. Luke looks through this, to the glory which was to follow. He steadfastly set his face - Without fear of his enemies, or shame of the cross, #Heb 12:2|.
Lu 9:51 When the time was come. The time of his suffering was not far away. He was about to leave Galilee. He stedfastly set his face to go to Jerusalem. Knowing what he should suffer there. Just when this was we are not told.
