Deuteronomio 15

All the firstling males that come of thy herd and of thy flock thou shalt sanctify unto the LORD thy God: thou shalt do no work with the firstling of thy bullock, nor shear the firstling of thy sheep.

Santificarás á Jehová tu Dios todo primerizo macho que nacerá de tus vacas y de tus ovejas: no te sirvas del primerizo de tus vacas, ni trasquiles el primerizo de tus ovejas.

You shall dedicate all the firstborn males that are born of your herd and of your flock to the LORD your God. You shall do no work with the firstborn of your herd, nor shear the firstborn of your flock.
