34 The blood is life itself. This is a figure of speech (metonymy) in which the cause or means (the blood) stands for the result or effect (life). That is, life depends upon the existence and circulation of blood, a truth known empirically but not scientifically tested and proved until the 17th century a.d. (cf. Lev 17:11).
