Exodus 17:5

Exo 17:5 And the LORD said unto Moses, Go on before the people, and take with thee of the elders of Israel; and thy rod, wherewith thou smotest the river, take in thine hand, and go.

Ver. 5. Take with thee of the elders. ] As witnesses of this great work of God; which the people for their unbelief might not behold. God puts up with their rebellion, and satisfies their thirst: but yet intimates his just displeasure, by denying them this privilege of seeing the rock smitten.
