Blood is the only atonement for sin.
Man lives only by the breath of God.
The aroma of the sacrifice pleases God.
God always sees the sacrifice of the giver.
Insects and porc.
Female goats and 2 day old manna.
The kidneys and the fat near the loins.
Fat and blood.
A large quantity of flour and a dove.
A female sheep that had not given birth.
A young bull without blemish.
A male goat without defect.
The burnt offering was to remain on the altar hearth until morning.
The priest must put on linen clothes before removing he ashes from the altar.
An additional change of clothes was required before carrying the ashes away.
The fire was to be kept burning continuously and was not allowed to go out.
All of the above were required.
Until the lord spoke.
Until seven animal sacrifices were completed.
Because they approached the altar without the "anointed robes" they were commanded to wear.
Because they offered profane fire to the Lord.
Because their hearts had hardened toward God.
Because Aaron had sinned before God and had not made an atoning sacrifice.
Blame God, abandon their duties as priests, forget the holy ordinances.
Leave the tabernacle, become unclean, eat forbidden meat.
Cry out to the Lord, tear their clothes, offer an unacceptable sacrifice.
Uncover their heads, tear their clothes, leave the tabernacle.
