Leviticus 8:32

And ye shall let nothing of it remain until the morning; and that which remaineth of it until the morning ye shall burn with fire.

And if ought of the flesh of the consecrations, or of the bread, remain unto the morning, then thou shalt burn the remainder with fire: it shall not be eaten, because it is holy.

But the remainder of the flesh of the sacrifice on the third day shall be burnt with fire.

Boast not thyself of to morrow; for thou knowest not what a day may bring forth.

Whatsoever thy hand findeth to do, do it with thy might; for there is no work, nor device, nor knowledge, nor wisdom, in the grave, whither thou goest.

(For he saith, I have heard thee in a time accepted, and in the day of salvation have I succoured thee: behold, now is the accepted time; behold, now is the day of salvation.)

But exhort one another daily, while it is called To day; lest any of you be hardened through the deceitfulness of sin.
