1 Samuel 28:10 Meaning and Commentary

1 Samuel 28:10

And Saul sware to her by the Lord
By the Word of the Lord, as the Targum: it is much that Saul, being about such a work of darkness and wickedness, could take the name of the Lord into his mouth, and swear by him in such a solemn manner; which must surely put him in mind of his omniscience, from whom this wicked action could not be hid:

saying, [as] the Lord liveth, there shall no punishment happen to thee
for this thing;
the tenor of the oath was, and so the woman understood it, that he would never make any discovery of what she did, and so she would be sat from punishment; though as he was the supreme governor, and a very arbitrary prince, had it been discovered, he could have screened her from justice, though contrary to the law of God; however, he could not secure her from eternal punishment.

1 Samuel 28:10 In-Context

8 Therefore Saul changed his clothing, and he was clothed with other clothes; and he went, and two men with him; and they came to the woman in the night. And he said, Divine thou to me in a fiend speaking in the womb, and raise thou up to me whom I shall say to thee (And he said, Call thou for me thy familiar spirit, and raise thou up for me whom I shall name to thee).

9 And the woman said to him, Lo! thou knowest how great things Saul hath done, and how he hath done away from the land witches, and false diviners (and how he hath done away with witches, and false diviners, from the land); why therefore settest thou treason to my life, that I be slain?

10 And Saul swore to her in the Lord, and said, The Lord liveth; for nothing of evil shall come to thee for this thing. (And Saul swore to her by the Lord, and said, As the Lord liveth; nothing of evil shall come to thee for this thing.)

11 And the woman said to him, Whom shall I raise up to thee? And he said, Raise thou Samuel up to me. (And the woman said to him, Whom shall I raise up for thee? And he said, Raise thou up Samuel for me.)

12 Soothly when the woman had seen Samuel, she cried with [a] great voice, and said to Saul, Why hast thou deceived me? for thou art Saul.
