George Haydock's Catholic Commentary
Psalms 77:70
Young. Hebrew also, "giving milk." David was actually with his father's flocks, when he was sent for by Samuel. Saul was also engaged in the pursuits of a country life when he was chosen king: and it would indeed have been difficult to find people of another description among the Israelites, as all followed some business. Cr\'9csus observed that he first of his race (Gyges) obtained his liberty and the throne at the same time, as he had kept the flocks of the preceding king. (Xenophon vii.)
