Job 1:3

His substance -Margin, or “cattle.” The word used hereמקנהmı̂qnehis derived fromקנהqânâh, to gain or acquire, to buy or purchase, and properly means anything acquired or purchased - property, possessions, riches. The wealth of nomadic tribes, however, consisted mostly in flocks and herds, and hence the word in the Scripture signifies, almost exclusively, property in cattle. The word, says Gesenius, is used “strictly” to denote sheep, goats, and neat cattle, excluding beasts of burden (compare Greekκτῆνοςktēnos, herd, used here by the Septuagint), though sometimes the word includes asses and camels, as in this place.
