2 Chronicles 35:6
Ver. 6. So kill the passover,.... In the manner, time, and place, and for the persons it should be killed:
and sanctify yourselves: by washing themselves and garments, that they might be fit for this service:
and prepare your brethren; prepare a lamb for your brethren, or instruct them how to perform their office that needed instruction:
that they may do according to the word of the Lord by the hand of Moses; celebrate the ordinance of the passover in all its rites, according to the law of Moses, at least in every rite in which they were more peculiarly concerned.
