The original command for palm branches is found in the ‘appointed times’ of Elohim. The Feast of Tabernacles was given as a mikrah or ‘rehearsal’ for this very future event. It included not only waving palm branches, but also fruit, willows, and myrtle. These branches were waved to the north, south, east and west to prophesy the days when there would be a gathering of peoples from all nations, who would come and worship the One on the Throne and the Lamb in Jerusalem.
