עַד־אָ֭בוֹא אֶל־מִקְדְּשֵׁי־אֵ֑ל אָ֝בִ֗ינָה לְאַחֲרִיתָֽם׃
Пока я не вошел в святилище Божие, и не рассмотрел их конец.
Rashi
Until I came to the sanctuaries of God, which are in Jerusalem, and saw what happened to Sennacherib. Then I understood the end of the wicked, that it is to destruction. Then I said, “All the good that comes to them is only slippery places; for the Holy One, blessed be He, makes their way slippery, that it should be easy and smooth, so that they should not put their heart to return to Him, and they should perish.”
Radak
Until. I have pondered in my heart to understand this with great toil, and I have not found until I delved into the thoughts of my heart, to the sanctuary of God. And that is the world of angels and spirits, for there lies the ultimate reward, for the goodness of this worldly existence does not endure. But in the end, it is the world of souls where the righteous are examined, as our Father Avinu (Abraham) said about their ultimate state.
