Hearkened - Nothing can be more characteristic of Moses, who combines on all occasions distrust of himself and singular openness to impressions, with the wisdom and sound judgment which chooses the best course when pointed out.

So Moses hearkened to the voice of his father in law,.... Considered what he said, weighed it well in his mind, and judged it good advice, and determined to follow it:

and did all that he had said; by choosing such men as he directed to, and committing the judgment of the people to them, as follows:

Moses followed this sage advice, and, as he himself explains in Deuteronomy 1:12-18, directed the people to nominate wise, intelligent, and well-known men from the heads of the tribes, whom he appointed as judges, instructing them to administer justice with impartiality and without respect of persons.

So Moses {k} hearkened to the voice of his father in law, and did all that he had said.

(k) Godly counsel should always be obeyed, even if it comes from our inferiors, for to such God often gives wisdom to humble those that are exalted, and to declare that one member has need of another.

18:24 So Moses hearkened unto the voice of his father - in - law. When he came to consider the thing, he saw the reasonableness of it, and resolved to put it in practice, which he did soon after, when he had received directions from God. Those are not so wise as they would be thought to be, who think themselves too wise to be counselled; for a wise man will hear, and will increase learning, and not slight good counsel, though given by an inferior.

18:13-27 Here is the great zeal and the toil of Moses as a magistrate. Having been employed to redeem Israel out of the house of bondage, he is a further type of Christ, that he is employed as a lawgiver and a judge among them. If the people were as quarrelsome one with another as they were with God, no doubt Moses had many causes brought before him. This business Moses was called to; it appears that he did it with great care and kindness. The meanest Israelite was welcome to bring his cause before him. Moses kept to his business from morning to night. Jethro thought it was too much for him to undertake alone; also it would make the administration of justice tiresome to the people. There may be over-doing even in well-doing. Wisdom is profitable to direct, that we may neither content ourselves with less than our duty, nor task ourselves beyond our strength. Jethro advised Moses to a better plan. Great men should not only study to be useful themselves, but contrive to make others useful. Care must be taken in the choice of the persons admitted into such a trust. They should be men of good sense, that understood business, and that would not be daunted by frowns or clamours, but abhorred the thought of a bribe. Men of piety and religion; such as fear God, who dare not to do a base thing, though they could do it secretly and securely. The fear of God will best fortify a man against temptations to injustice. Moses did not despise this advice. Those are not wise, who think themselves too wise to be counselled.
