Exodus 15:18

The Lord shall reign forever and ever. The singer here rises to the greatest heights of exultation and looks even beyond the temporal kingdom of Israel in the Land of Promise, to the eternal reign of the Messiah.

And when they did mete it with an omer, the measure which the Lord had given as the standard, he that gathered much had nothing over, and he that gathered little had no lack; they gathered every man according to his eating. By God's miraculous arrangement the amounts gathered were just sufficient for each family and for the entire people.
