וְעָשִׂ֤יתָ עֹלֹתֶ֙יךָ֙ הַבָּשָׂ֣ר וְהַדָּ֔ם עַל־מִזְבַּ֖ח יְהוָ֣ה אֱלֹהֶ֑יךָ וְדַם־זְבָחֶ֗יךָ יִשָּׁפֵךְ֙ עַל־מִזְבַּח֙ יְהוָ֣ה אֱלֹהֶ֔יךָ וְהַבָּשָׂ֖ר תֹּאכֵֽל׃
and thou shalt offer thy burnt-offerings, the flesh and the blood, upon the altar of the LORD thy God; and the blood of thy sacrifices shall be poured out against the altar of the LORD thy God, and thou shalt eat the flesh.
