One of the lessons is because Moshe had a greater obligation of gratitude to the water & the earth.
This serves to remind us to thank Hashem for the water which pours out of the faucets when we use them. And to be thankful that you are standing on solid ground as you are reading this dvar Torah.
Thank You Hashem for the earth & the water.
Now may be a good time for a gem of Torah study.
