Psalms 78:71

71.He took him from following the suckling ewes, etc. The grace of God is farther commended from the circumstance, that David, who was a keeper of sheep, was made the shepherd of the chosen people and heritage of God. There is an allusion to David’s original condition; but the Spirit of God, at the same time, shows us the difference between good and lawful kings, and tyrants, robbers, and insatiable extortioners, by telling us that whoever would aspire to the character of the former must be like shepherds.

It is afterwards added, (verse 72,) that David had faithfully performed the duties of the trust committed to him. By this the prophet indirectly rebukes the ingratitude and perverseness of the people, who not only overturned the holy and inviolable order which God had established, but who had also, in shaking off his salutary yoke, thrown themselves into a state of miserable dispersion. What follows concerning the prudence of David’s hands seems to be an improper form of expression. But it is intended forcibly to express, that he not only was successful in what he had undertaken, but that he was governed by the Spirit of God, which prevented him from putting his hand at random to any work which might come in his way, and led him prudently and skilfully to do that to which faith and duty called him; and thus, in the success of his undertakings, his wisdom appears more conspicuous than his good fortune.
