ציטירנדיקער פּירוש אויף מלכים א 7:12

right this feminine adjective modifies the first of two nouns, as in “the inner [feminine] gate [feminine] of the court [masculine]” [I Kings 7:12]. I shall give the reason for the lobe and the thumb in the parasha of Meṣora‘ [comment on 14:14]. We see here that blood secures atonement for Aaron’s soul, as it is stated: “for the blood atones with the soul” [17:11] — meaning, it atones through the spirit of life which it formerly contained, in the sense of “a soul for a soul” [Exodus 21:23]. The phrase “she cast it down at his feet” [Exodus 4:25] addresses a similar idea.
