Commentaries:
Jamieson, Fausset, and Brown
The Lord spake unto Moses and Aaron, Because ye believed me not, etc.—The act of Moses in smiting twice betrayed a doubt, not of the power, but of the will of God to gratify such a rebellious people, and his exclamation seems to have emanated from a spirit of incredulity akin to Sarai's (Genesis 18:13). These circumstances indicate the influence of unbelief, and there might have been others unrecorded which led to so severe a chastisement.
there was no water for the congregation—There was at Kadesh a fountain, En-Mishpat (Genesis 14:7), and at the first encampment of the Israelites there was no want of water. It was then either partially dried up by the heat of the season, or had been exhausted by the demands of so vast a multitude.
