'Palm branches' in the Bible

On the following day great numbers of people who had come to the Festival, hearing that Jesus was on his way to Jerusalem, took palm-branches,

After this, in my vision, I saw a vast throng which no man could number, of men from every nation and of all tribes, and peoples, and languages. They stood in front of the throne and in front of the Lamb, robed in white, holding palm branches in their hands.
