1 Kings 18:10

10 By the living Lord, your God, I swear that the king has made a search for you in every country in the world. Whenever the ruler of a country reported that you were not in his country, Ahab would require that ruler to swear that you could not be found.

1 Kings 18:10 Meaning and Commentary

1 Kings 18:10

As the Lord thy God liveth
Which is the form of an oath he thought fit to make, to ascertain the truth of what he was about to say: there is no nation or kingdom, whither my lord hath not sent to seek
thee;
which is either an hyperbolical expression, signifying he had sought for him in many places, and in every place he could think of; or it must be understood either of the ten tribes, which were as so many nations and kingdoms as they had been; or were more in the times of the Canaanites; or of the nations round about, that were in alliance with or tributary to the king of Israel: and when they said, he is not there, he took an oath of the kingdom and
nation that they found thee not;
which he might exact of his own subjects, but could not of other nations, unless they were free to it of themselves; or he might take it of their ambassadors or merchants that came into his land, of whom he inquired, and adjured them to tell him the truth.

1 Kings 18:10 In-Context

8 "Yes, I'm Elijah," he answered. "Go and tell your master the king that I am here."
9 Obadiah answered, "What have I done that you want to put me in danger of being killed by King Ahab?
10 By the living Lord, your God, I swear that the king has made a search for you in every country in the world. Whenever the ruler of a country reported that you were not in his country, Ahab would require that ruler to swear that you could not be found.
11 And now you want me to go and tell him that you are here?
12 What if the spirit of the Lord carries you off to some unknown place as soon as I leave? Then, when I tell Ahab that you are here and he can't find you, he will put me to death. Remember that I have been a devout worshiper of the Lord ever since I was a boy.
