Verse 10. - Their bull gendereth, and faileth not; rather, their cow conceiveth . Shor (שׁור), which is of both genders, must here be taken as feminine. Their cow (rather, their heifer) calveth, and casteth not her calf. Both conception and birth are prosperous; there is neither barrenness nor abortion.

21:7-16 Job says, Remarkable judgments are sometimes brought upon notorious sinners, but not always. Wherefore is it so? This is the day of God's patience; and, in some way or other, he makes use of the prosperity of the wicked to serve his own counsels, while it ripens them for ruin; but the chief reason is, because he will make it appear there is another world. These prospering sinners make light of God and religion, as if because they have so much of this world, they had no need to look after another. But religion is not a vain thing. If it be so to us, we may thank ourselves for resting on the outside of it. Job shows their folly.Their bull gendereth, and faileth not,.... As the wicked man's prosperity is described before by the increase and comfortable settlement of his children and grandchildren, and by the peace and safety of all within doors; here it is further set forth by the increase of his cattle in the fields, one part being put for the whole, his oxen and asses, his camels and sheep, things in which the riches of men chiefly lay in those times and countries; and he was reckoned an happy man when these brought forth abundantly; see Psalm 144:13;

their cow calveth, and casteth not her calf; both male and female succeed in propagating their species, and so in increasing the wealth of their owner; this is sometimes promised as a temporal blessing, Exodus 23:26.
