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 And Saul disguised himself and put on other clothing, and he went with two men, and they came to the woman by night; and he said, I pray thee, divine unto me by spiritism and bring me him up whom I shall name unto thee.

9 And the woman said unto him, Behold, thou knowest what Saul has done, how he has cut off the spiritists and the diviners out of the land; why then dost thou lay a snare for my life, to cause me to die?

10 And Saul swore to her by the LORD, saying, As the LORD lives, no iniquity shall come upon thee for this thing.

11 Then the woman said, Whom shall I bring up unto thee? And he said, Bring me up Samuel.

12 And when the woman saw Samuel, she cried with a loud voice; and the woman spoke to Saul, saying, Why hast thou deceived me? For thou art Saul.
