'Palm branches' in the Bible

On the first day you must take for yourselves branches from majestic trees -- palm branches, branches of leafy trees, and willows of the brook -- and you must rejoice before the Lord your God for seven days.

After these things I looked, and here was an enormous crowd that no one could count, made up of persons from every nation, tribe, people, and language, standing before the throne and before the Lamb dressed in long white robes, and with palm branches in their hands.
