וְהֵבִ֣יא אֶת־אֲשָׁמ֣וֹ לַיהוָ֡ה עַ֣ל חַטָּאתוֹ֩ אֲשֶׁ֨ר חָטָ֜א נְקֵבָ֨ה מִן־הַצֹּ֥אן כִּשְׂבָּ֛ה אֽוֹ־שְׂעִירַ֥ת עִזִּ֖ים לְחַטָּ֑את וְכִפֶּ֥ר עָלָ֛יו הַכֹּהֵ֖ן מֵחַטָּאתֽוֹ׃
and he shall bring his forfeit unto the LORD for his sin which he hath sinned, a female from the flock, a lamb or a goat, for a sin-offering; and the priest shall make atonement for him as concerning his sin.
