וְנָתַ֧ן אֶֽת־הַקְּטֹ֛רֶת עַל־הָאֵ֖שׁ לִפְנֵ֣י יְהוָ֑ה וְכִסָּ֣ה ׀ עֲנַ֣ן הַקְּטֹ֗רֶת אֶת־הַכַּפֹּ֛רֶת אֲשֶׁ֥ר עַל־הָעֵד֖וּת וְלֹ֥א יָמֽוּת׃
And he shall put the incense upon the fire before the LORD, that the cloud of the incense may cover the ark-cover that is upon the testimony, that he die not.
Targum Jonathan on Leviticus
And he shall put the sweet incense upon the fire before the Lord, and the cloud of the fuming incense shall envelope the mercy-seat that is over the testimony, that he may not die by the flaming fire before the Lord.
