וְלֹֽא־תַעֲלֶ֥ה בְמַעֲלֹ֖ת עַֽל־מִזְבְּחִ֑י אֲשֶׁ֛ר לֹֽא־תִגָּלֶ֥ה עֶרְוָתְךָ֖ עָלָֽיו׃ (פ)
Targum Jonathan on Exodus
And you, the priests, who stand to minister before Me, shall not ascend to My altar by steps, but by (sloping) bridges; that thy shame may not be seen thereupon.
Targum Jerusalem
You also, the priests, the sons of Aharon, who stand and minister beside Mine altar, shall not ascend by steps unto Mine altar, lest your shame be disclosed upon it.
