As a shepherd inspects his flock
In a word: As a shepherd watches over his flock (the word "cow" means "hearing carefully, watching").
("As a shepherd inspects his flock on the day he is among his scattered sheep, so I will inspect my sheep and deliver them from all the places to which they were scattered on a day of cloud and thick darkness" - Ezekiel 34:12, and also: "Like a shepherd inspecting his flock, passing his sheep under his staff, so shall You pass, count, appoint, and examine the life of every living being, and assign a measure to every creature and write down their judgment" - from the piyyut "Unetanneh Tokef" recited in the High Holiday prayers, and also: "For the day shall come, a cry of death, like a shepherd He will inspect his flock: He will roar and pass on like a lion, and be separated as He goes" - Judah al-Harizi (12th century) / heavy hands).
