Thank you for the question of intercalation in the Gospel of Mark, “What is the sample of intercalation or sandwich in the Gospel of Mark?”
One would expect intercalation or interruption of events in the life of Jesus. We have interruptions all that time. It’s normal and expected.
We have experience our children or spouse call us from something that we are doing. We lay it aside and attend to what is needed from the other person. When that task is finished, we resume our initial work.
As one reads the Gospels or even Acts, we expect to find that happening in the life of Jesus. An example would be Mark 14 of Jesus is dining at the home of Simon the Leper. The writer doesn’t record the conversation around the dinner table. The meal is interrupted with a woman breaking that expensive jar of “perfume” and pouring it on his head. The whole conversation changes from what they were talking about to talking about the woman’s action and waste.
Mark 14 says this, “While he was in Bethany, reclining at the table in the home of Simon the Leper, a woman came with an alabaster jar of very expensive perfume, made of pure nard. She broke the jar and poured the perfume on his head. 4 Some of those present were saying indignantly to one another, “Why this waste of perfume? 5 It could have been sold for more than a year’s wages[a] and the money given to the poor.” And they rebuked her harshly. 6 “Leave her alone,” said Jesus. “Why are you bothering her? She has done a beautiful thing to me. 7 The poor you will always have with you,[b] and you can help them any time you want. But you will not always have me. 8 She did what she could. She poured perfume on my body beforehand to prepare for my burial. 9 Truly I tell you, wherever the gospel is preached throughout the world, what she has done will also be told, in memory of her.” 10 Then Judas Iscariot, one of the Twelve, went to the chief priests to betray Jesus to them. 11 They were delighted to hear this and promised to give him money. So he watched for an opportunity to hand him over.” (NIV).
In the next event recorded by the writer of the Gospel of Mark, Jesus interrupts the meal by declaring that one of the will betray him and then they resume the meal with a song before they leave for the Mount of Olives (Mark 14:17–26).
SUMMARY: The interruptions of Jesus’ life have a purpose that provides greater insight as to the importance of what Jesus was doing or what will happen to him. Don’t ignore the interruptions of our lives. There is a reason for our attention to it.
