I am not able to bear all this people alone,.... The burden of government of them, to take care of them and provide sustenance for them; but he was not alone, for, not to take notice of the rulers and officers in the several divisions of the people that assisted and eased him in lighter matters, advised to by Jethro, Exodus 18:21, the Lord himself was with him in all matters of moment and difficulty; to whom he could apply at any time for advice, and who had promised to supply and did supply the people with suitable and proper provisions every day:
because it is too heavy for me; to answer the requests, redress the grievances, and supply the necessities of this people.

To bear - The burden of providing for and satisfying them. Alone - Others were only assistant to him in smaller matters; but the harder and greater affairs, such as this unquestionably was, were brought to Moses and determined by him alone.
