Note 2 — Chapter XV · Satan.

Satan, among the Jews, was at first a generic term for an adversary lying in wait. It is probably the furtive suggestion at the root of this Hebrew word which aided in its selection as the name for the invisible adverse powers when they were especially distinguished. But originally no special personage, much less any antagonist of Jehovah, was signified by the word. Thus we read: ‘And God’s anger was kindled because he (Balaam) went; and the angel of the Lord stood in the way for a Satan against him.... And the ass saw the angel of the Lord standing in the way and his sword drawn in his hand.’2 The eyes of Balaam are presently opened, and the angel says, ‘I went out to be a Satan to thee because the way is perverse before me.’ The Philistines fear to take David with them to battle lest he should prove a Satan to them, that is, an underhand enemy or traitor.3 David called those who wished to put Shimei to death Satans;4 but in this case the epithet would have been more applicable to himself for affecting to protect the honest man for whose murder he treacherously provided.5
