Darby

19 Every firstling that is born among thy kine and among thy sheep that is a male, thou shalt hallow to Jehovah thy God: thou shalt do no work with the firstling of thy kine, nor shear the firstling of thy sheep.

KJV

19 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.
