All the firstborn males that are born of your herd and of your flock you shall sanctify to Yahweh your God: you shall do no work with the firstborn of your herd, nor shear the firstborn of your flock.

because you trespassed against me in the midst of the children of Israel at the waters of Meribah of Kadesh, in the wilderness of Zin; because you didn't sanctify me in the midst of the children of Israel.
