Do not substitute another beast for one set apart for sacrifice

'He shall not replace it or exchange it, a good for a bad, or a bad for a good; or if he does exchange animal for animal, then both it and its substitute shall become holy.

Hebrew

י לֹא יַחֲלִיפֶנּוּ, וְלֹא-יָמִיר אֹתוֹ טוֹב בְּרָע--אוֹ-רַע בְּטוֹב; וְאִם-הָמֵר יָמִיר בְּהֵמָה בִּבְהֵמָה, וְהָיָה-הוּא וּתְמוּרָתוֹ יִהְיֶה-קֹּדֶשׁ.

Greek

10 οὐκ ἀλλάξει αὐτὸ καλὸν πονηρῷ οὐδὲ πονηρὸν καλῷ· ἐὰν δὲ ἀλλάσσων ἀλλάξῃ αὐτὸ κτῆνος κτήνει, ἔσται αὐτὸ καὶ τὸ ἄλλαγμα ἅγια.
