Palm Sunday is a Christian moveable feast that falls on the Sunday before Easter. The feast commemorates Jesus' triumphal entry into Jerusalem.
It is referred to as Palm Sunday because of the palm branches that were laid on the road as Jesus rode the donkey into Jerusalem.
John 12:12-15 ESV
(12)The next day the large crowd that had come to the feast heard that Jesus was coming to Jerusalem.
(13)So they took branches of palm trees and went out to meet him, crying out, “Hosanna! Blessed is he who comes in the name of the Lord, even the King of Israel!”
(14)And Jesus found a young donkey and sat on it, just as it is written,
(15)“Fear not, daughter of Zion; behold, your king is coming, sitting on a donkey's colt!”
Wishing Everyone a Blessed Palm Sunday!
