Do not work consecrated animals

"You shall consecrate to the LORD your God all the firstborn males that are born of your herd and of your flock; you shall not work with the firstborn of your herd, nor shear the firstborn of your flock.

Hebrew

יט כָּל-הַבְּכוֹר אֲשֶׁר יִוָּלֵד בִּבְקָרְךָ וּבְצֹאנְךָ, הַזָּכָר--תַּקְדִּישׁ, לַיהוָה אֱלֹהֶיךָ: לֹא תַעֲבֹד בִּבְכֹר שׁוֹרֶךָ, וְלֹא תָגֹז בְּכוֹר צֹאנֶךָ.

Greek

19 Πᾶν πρωτότοκον, ὃ ἐὰν τεχθῇ ἐν τοῖς βουσίν σου καὶ ἐν τοῖς προβάτοις σου, τὰ ἀρσενικά, ἁγιάσεις κυρίῳ τῷ θεῷ σου· οὐκ ἐργᾷ ἐν τῷ πρωτοτόκῳ μόσχῳ σου καὶ οὐ μὴ κείρῃς τὸ πρωτότοκον τῶν προβάτων σου·
