אַךְ־בְּכ֞וֹר אֲשֶׁר־יְבֻכַּ֤ר לַֽיהוָה֙ בִּבְהֵמָ֔ה לֹֽא־יַקְדִּ֥ישׁ אִ֖ישׁ אֹת֑וֹ אִם־שׁ֣וֹר אִם־שֶׂ֔ה לַֽיהוָ֖ה הֽוּא׃
Howbeit the firstling among beasts, which is born as a firstling to the LORD, no man shall sanctify it; whether it be ox or sheep, it is the LORD’S.
Targum Jonathan on Leviticus
Moreover, the firstling among cattle which is separated to the Name of the Lord, whether ox or lamb, a man cannot separate (as a votive gift), because it (already belongeth) to the Name of the Lord.
Targum Jerusalem
But the firstling among cattle, whether ox or lamb, which is separated before the Lord, belongeth (already) to the Name of the Lord.
