Charles Ellicott Commentary 1 Kings 19:18

"Yet will I leave [me] seven thousand in Israel, all the knees which have not bowed unto Baal, and every mouth which hath not kissed him." — 1 Kings 19:18 (ASV)

I have left. —It should be “I leave,” or “will leave,” through all this vengeance, the seven thousand faithful; like the faithful remnant sealed in the visions of Ezekiel and St. John in the day of God’s judgment (Ezekiel 9:4–6; Revelation 7:3–8).

Kissed him. —(Hosea 13:2.) The passage is vividly descriptive of the worshipper on the first approach bowing the knee, on nearer access kissing the image, or the altar, or the threshold of the temple.
