“And the Jews’ passover was nigh at hand: and many went out of the country up to Jerusalem before the passover, to purify themselves.”
John 11:55 — Greek Interlinear
Church Fathers on John 11:55
After this resolution of the Chief Priests and Pharisees, Jesus was more cautious in strewing Himself among the Jews, and retired to remote parts, and avoided populous places: Jesus therefore walked no more openly among the Jews; but went from there into a country near to the wilderness, into a city called Ephraim.
Not that His power had failed Him; for, had He pleased He might still have walked openly among the Jews, and they done nothing to Him. But He wished to show the disciples, by His own example, that believers did not sin by retiring out of the sight of their persecutors, and hiding themselves from the fury of the wicked, rather than inflame that fury in their presence.
How must it have troubled the disciples to see Him save Himself by merely human means? While all were rejoicing and keeping the feast, they remained hidden, and in danger. Yet they continued with Him; as we read in Luke, You are they which have continued with Me in My temptations.
