"A few days before the final Passover, Jesus drew near to Jerusalem (John 11:55), arriving at Bethany six days before Passover (John 12:1), namely the Saturday before the Passion Week. That evening, Jesus was anointed at Simon the Leper's house (Matt. 26:6-13; Mk. 14:3-9; John 12:1-8). On the next day (Sunday), there was a great crowd that came to Bethany to see Jesus (John 12:9-11).We should not allow the proposal that Jesus' triumphal entry might have happened on Monday bother us. There is nothing theological hinging on a Sunday entry. It is simply the day traditionally recognized. The thing that we should allow to ring in our minds is that Jesus Christ came into Jerusalem in order to be God's perfect sacrifice.
The next day, Monday (John 12:12), was Jesus' triumphal entry into Jerusalem (Matt. 21:1-9; Mk. 11:1-10; Lk. 19:28-40; John 12:12-19), His visit to the temple (Matt. 21:10-11; Mk. 11:11), and then His return to Bethany. The day of the triumphal entry would be Nissan 10 when the lamb was selected for Passover. Hence, the triumphal entry was the day when Christ presented Himself as Israel's Paschal lamb."
In Exodus 12:1-6, as God was preparing His final judgment on Egypt, He gave the command and procedure for Passover. Each family was to choose a lamb on the 10th day of that month and examine it for 4 days to prove that it was pure and free from defect. Then, on the 14th day, the lamb was to be slain. Jesus Christ, God the Son, was selected by God the Father as a lamb without spot or blemish - God's perfect Lamb (Rev. 5:6-10). Then, over the next 4 days (Mon.-Thur.), He was examined. Examine Him. See, as you read, that He is pure and without defect. He is without one spot of sin. His worth is immeasurable.
God, help us to see your Son, God the Son, as the Lamb this week.
