וְעָשִׂ֥יתָ מִזְבֵּ֖חַ מִקְטַ֣ר קְטֹ֑רֶת עֲצֵ֥י שִׁטִּ֖ים תַּעֲשֶׂ֥ה אֹתֽוֹ׃
Farás um altar para queimar o incenso; de madeira de acácia o farás.
Shulchan Arukh, Orach Chayim
One should recite along with the sacrifice passages the verse: "And he shall slaughter it on the side of the altar northward before the Lord...." (Leviticus 1:11).
