a place to stop for the night on a journey: the spot where travelers halt, whether or not anything is built there
This word is built from the ordinary verb for spending the night (לוּן), and it names the place where that happens: the spot a traveling party stops when the day's walking is done. It is a word about a journey, never about a home. Nobody lives at one of these places. People arrive at dusk, sleep, and move on in the morning.
The picture is usually far plainer than the old English rendering "inn" suggests. When Joseph's brothers open a sack at the stopping place and find their silver back inside it, and when God meets Moses on the road at the stopping place, nothing in the text points to a building, a keeper, or a paid room. It is simply where they halted. Joshua uses the same word for the whole nation's one night beside the Jordan, and Isaiah uses it for the night halt of an advancing army.
The word can also lean toward an actual shelter. Jeremiah wishes he had a travelers' lodging out in the desert, a rough place to hole up in, which is why he can picture it as somewhere to run away to. And once it stretches away from sleeping altogether: in the boast of the Assyrian king it marks the last stop at the far edge of Lebanon, the point past which there is nowhere further to go.
Two neighbors are worth keeping clear of it. A camp (מַחֲנֶה) is a settled body of tents that can stand for months, and a dwelling (מָעוֹן) is where someone actually lives. This word means one night, on the way to somewhere else.
Nuances
Whether this word stands in 2 Kings 19:23 at all: the written consonants give "his farthest lodging place", while the traditional reading and the parallel line in Isaiah 37:24 give a word meaning "height".
- majorityRead "height" with the reading tradition and the Isaiah 37:24 parallel, so the boast is about reaching the highest peaks of Lebanon.; HALOT, s.v. מָלוֹן
- minorityKeep the written form and take the phrase as the farthest lodging place of Lebanon, the last halt at its edge.; BDB, s.v. מָלוֹן
