Fat a symbol for SIN...
But the wicked shall perish,
and the enemies of the LORD shall be as the fat of lambs:
they shall consume; into smoke shall they consume away.
Psalm 37:20
But Jeshurun waxed fat, and kicked:
thou art waxen fat, thou art grown thick,
thou art covered with fatness;
then he forsook God which made him, and lightly esteemed the Rock of his salvation.
Deuteronomy 32:15
The FAT (SIN) is taken away in the Atonement for those who repent...
And he shall take away all the fat thereof,
as the fat is taken away from off the sacrifice of peace offerings;
and the priest shall burn it upon the altar for a sweet savor unto the LORD;
and the priest shall make an atonement for him,
and it shall be forgiven him.
Leviticus 4:31
