סֶ֣לַע יִ֭שְׁכֹּן וְיִתְלֹנָ֑ן עַֽל־שֶׁן־סֶ֝֗לַע וּמְצוּדָֽה׃
She dwelleth and abideth on the rock, Upon the crag of the rock, and the stronghold.
Rashi on Job
He dwells on the rock and lodges Aaron was confident when he placed the censer with the incense on the foundation stone [in the Holy of Holies].
