Melachim Alef 18:10

10 As Hashem Eloheicha liveth, there is no goy (nation) or mamlachah (kingdom), to where adoni hath not sent to seek thee there: and when they said, He is not there, he had the mamlachah and goy swear, that they found thee not.

Melachim Alef 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.

Melachim Alef 18:10 In-Context

8 And he answered him, I am; go, tell adoneicha, Hinei, Eliyahu!

9 And he said, What have I sinned, that thou wouldest deliver thy eved into the yad Ach’av to slay me?

10 As Hashem Eloheicha liveth, there is no goy (nation) or mamlachah (kingdom), to where adoni hath not sent to seek thee there: and when they said, He is not there, he had the mamlachah and goy swear, that they found thee not.

11 And now thou sayest, Go, tell adoneicha, Hinei, Eliyahu!

12 And it shall come to pass, as soon as I am gone from thee, that the Ruach [Hakodesh] of Hashem shall carry thee to where I know not; and so when I come and tell Ach’av, and he cannot find thee, he shall slay me; but I thy eved fear Hashem from my youth.
