shall not eat any thing with the blood - (See on Lev 17:10).
neither ... use enchantment, nor observe times - The former refers to divination by serpents - one of the earliest forms of enchantment, and the other means the observation, literally, of clouds, as a study of the appearance and motion of clouds was a common way of foretelling good or bad fortune. Such absurd but deep-rooted superstitions often put a stop to the prosecution of serious and important transactions, but they were forbidden especially as implying a want of faith in the being, or of reliance on the providence of God.
