Four Species Hallel Paragraph Two

“Who turned the rock into a pool of water. Pebbles into a source of water.” God uses His creation at will to do as He wishes. The Midrash teaches that God made a condition with each creation before it assumed its form, to serve certain functions. The creations took this a step further:
“The Sea saw it and ran away.
The Jordan River reversed course.
The mountains danced like deer,
the hills like lambs.”

The creations independently respond to God’s manifestations, not only to His commands and wishes. The Four Species dance in our hands to the Hallel as if to express for all of creation, their honor of Him.
