Matthew Henry Commentary Deuteronomy 1:9-18

"And I spake unto you at that time, saying, I am not able to bear you myself alone: Jehovah your God hath multiplied you, and, behold, ye are this day as the stars of heaven for multitude. Jehovah, the God of your fathers, make you a thousand times as many as ye are, and bless you, as he hath promised you! How can I myself alone bear your cumbrance, and your burden, and your strife? Take you wise men, and understanding, and known, according to your tribes, and I will make them heads over you. And ye answered me, and said, The thing which thou hast spoken is good [for us] to do. So I took the heads of your tribes, wise men, and known, and made them heads over you, captains of thousands, and captains of hundreds, and captains of fifties, and captains of tens, and officers, according to your tribes. And I charged your judges at that time, saying, Hear [the causes] between your brethren, and judge righteously between a man and his brother, and the sojourner that is with him. Ye shall not respect persons in judgment; ye shall hear the small and the great alike; ye shall not be afraid of the face of man; for the judgment is God`s: and the cause that is too hard for you ye shall bring unto me, and I will hear it. And I commanded you at that time all the things which ye should do." — Deuteronomy 1:9-18 (ASV)

Moses reminds the people of the beneficial arrangement of their government, which could make them all secure and at ease, if it were not their own fault. He acknowledges the fulfillment of God's promise to Abraham and prays for its further accomplishment.

We are not restricted by the power and goodness of God; why then should we be restricted in our own faith and hope?

Good laws were given to the Israelites, and good men were to oversee their execution, which demonstrated God's goodness to them and the care of Moses.
