Job 1:14

And there came a messenger unto Job -Hebrewמלאךmal'âk; the word usually rendered “angel,” appropriately rendered “messenger” here. The word properly means “one who is sent.” The oxen were plowing -Hebrew “the cattle” (בקרbâqâr) including not merely “oxen,” but probably also “cows;” see the notes atJob 1:3. And the asses -Hebrewאתון'âthôn“she-asses.” The “sex” is here expressly mentioned and Dr. Good maintains that it should be in the translation. So it is in the Septuagintαἱ θήλειαι ὄνοιhaithēleiaionoi. So Jerome, “asinoe.” The reason why the sex is specified is, that female asses, on account of their milk, were much more valuable than males.
