And Adonoy spoke to Moses to say:

Make a copper laver

and a copper base, for washing;

and place it

between the Tent of Meeting and the Altar,

and put water in it.

Aaron and his sons will wash from it,

their hands and their feet.¹

footnotes: ¹ His right hand was held above his right foot, the left hand above the left foot and all were washed simultaneously.—Maseches Zevachim 59

Upon entering the Tent of Meeting

they will wash with water that they not die,

or whenever they approach the Altar

to serve, to burn a fire-offering to Adonoy.

They will wash their hands and feet

that they not die;

and this is for them a perpetual statute

for him [Aaron], and his descendants

for all their generations.

And Adonoy spoke to Moses to say:

Command Aaron and his sons to say,

this is the law of the burnt-offering.

This is the burnt-offering

[which must remain] on its pyre,

upon the Altar all night,

until morning,

and the fire of the Altar

will be kept burning on it.

The Kohein will don his linen garment,

and linen breeches upon his flesh,

and he will remove the ashes

when the fire consumes

the burnt-offering on the Altar;

and he will place them beside the Altar.

He will remove his garments

and don other garments,

and carry the ashes

outside the camp

to an undefiled place.

The fire upon the altar will be kept burning,

it may not be extinguished.

And the Kohein will burn wood on it

every morning,

and arrange on it the burnt-offering,

and burn on it the fats of the peace-offerings.

A constant fire

will be kept burning on the Altar,

it may not be extinguished.
