Palm Sunday marks the beginning of Holy Week when the Lord Jesus made his triumphal entry into Jerusalem. All four Gospels record this historical event.
On Holy Monday, the Lord Jesus clears the Temple. Luke 19: 46. Then, on Holy Tuesday, Jesus goes to the Mount of Olives. Biblical scholars speculate that on Wednesday Jesus and His disciples rested in anticipation of Passover. However there is no biblical record of this in the Gospels.
Holy Week continues with Passover and the Last Supper/ Maundy Thursday. From Bethany, Jesus sent Peter and John to the Upper Room to make preparation for the Passover Meal.
It is important to note that Holy Week, Passover, and the Last Supper has no mention of the word Easter. When we focus on the biblical text/scriptures, we will discover the accurate record of the Lord Jesus his trial, death, burial, and resurrection.
I recently attended a Passover Seder. Our hosts, Jewish Believers helped Christians understand the Biblical significance for the Passover and the Lord Jesus the Lamb of God who takes away the sins of the world.
