כָּל־מַלְכֵ֥י גוֹיִ֖ם כֻּלָּ֑ם שָׁכְב֥וּ בְכָב֖וֹד אִ֥ישׁ בְּבֵיתֽוֹ׃
Tous les rois des nations sont couchés avec honneur, chacun dans son mausolée;
Radak
וישא לוט את עיניו, from the mountain where they were staying, as we know from 12,8. Seeing that this was a high point in the country, it afforded Lot an opportunity to survey much of the rest of the country all around him. As a result, he observed כי כלה משקה, that the Jordan valley was very well irrigated. When the Torah uses the word כלה after having already said כל when describing the valley, this is a way of emphasising the word כל still further. We find a similar construction in Isaiah 14,18 כל מלכי גוים כולם, “all the kings of the nations, all of them.”
