Variantly: "for an ox, for an ass": Why is this stated? Because it is written (earlier [6]) "If a man give to his neighbor money or vessels, etc." and (later 9]) "If a man give to his neighbor an ox or a lamb, etc.", Scripture comes here [8] to discriminate between (the first) watcher, (an unpaid watcher), and the second, (a paid watcher). But perhaps Scripture comes to differentiate between [6] "money or vessels" and [9] "beast"? It is, therefore, written [8] "for an ox, for an ass," (indicating that this is not its purpose, but, rather to discriminate between watcher and watcher.)
