לֹ֣א יַחֲלִיפֶ֗נּוּ וְלֹֽא־יָמִ֥יר אֹת֛וֹ ט֥וֹב בְּרָ֖ע אוֹ־רַ֣ע בְּט֑וֹב וְאִם־הָמֵ֨ר יָמִ֤יר בְּהֵמָה֙ בִּבְהֵמָ֔ה וְהָֽיָה־ה֥וּא וּתְמוּרָת֖וֹ יִֽהְיֶה־קֹּֽדֶשׁ׃
He shall not alter it, nor change it, a good for a bad, or a bad for a good; and if he shall at all change beast for beast, then both it and that for which it is changed shall be holy.
Targum Jonathan on Leviticus
He shall not alter it nor change it, that which is perfect for that which hath blemish, or that in which there is blemish for the perfect: but if by changing he will exchange animal for animal, both that and the one that is changed shall be consecrate.
Targum Jerusalem
And he shall not change it, good for bad, or bad for good: but if changing he will exchange animal for animal, both that and his changed one shall be sacred.
