Their bull breeds, and fails not; their cow calves, and casts not her calf.
All Commentaries on Job 21:10 Go To Job 21
Gregory The Dialogist
AD 604
It is the usage of common talk to call ‘ox [bos]’ masculine, and ‘cow’ feminine, but literary phraseology designates ‘ox’ of the common gender. Hence it is now said, Their ox conceiveth, and faileth not; their cow calveth, and loseth not her calf. For to the owner of flocks, the first good fortune is that the flocks being free from barrenness conceive, next that the conception come to the birth, and the third that the thing which is produced be by nourishment reared to a growth. And so in order to shew that the wicked had them all together, blessed Job declares that ‘their flocks had conceived and not miscarried, that they had brought forth and were not deprived of their own offspring.’ But it is inferior good fortune, if whilst the flocks increase, the keepers of them do not thrive at the same time. And hence to the fruitfulness of the flocks we have the fruitfulness of their household [familiae] made to succeed immediately.
