אַ֣ךְ בְּֽכוֹר־שׁ֡וֹר אֽוֹ־בְכ֨וֹר כֶּ֜שֶׂב אֽוֹ־בְכ֥וֹר עֵ֛ז לֹ֥א תִפְדֶּ֖ה קֹ֣דֶשׁ הֵ֑ם אֶת־דָּמָ֞ם תִּזְרֹ֤ק עַל־הַמִּזְבֵּ֙חַ֙ וְאֶת־חֶלְבָּ֣ם תַּקְטִ֔יר אִשֶּׁ֛ה לְרֵ֥יחַ נִיחֹ֖חַ לַֽיהוָֽה׃
But the firstling of an ox, or the firstling of a sheep, or the firstling of a goat, thou shalt not redeem; they are holy: thou shalt dash their blood against the altar, and shalt make their fat smoke for an offering made by fire, for a sweet savour unto the LORD.
