바이크라 (레위기) 14:57

להורת ביום הטמא — This may be translated: TO GIVE INSTRUCTION "CONCERNING" THE DAY OF ITS BEING UNCLEAN, i. e. which day renders it clean and which day renders it unclean (to point out that particular day on which, according to circumstances, a house or a garment or a person is to be declared clean or unclean).

לְהוֹרֹ֕ת בְּי֥וֹם הַטָּמֵ֖א וּבְי֣וֹם הַטָּהֹ֑ר זֹ֥את תּוֹרַ֖ת הַצָּרָֽעַת׃ {פ}

to teach when it is unclean, and when it is clean: this is the Tora of żara῾at.
