Exodus 29:13
Take all the fat that covers the entrails and the lobe of the liver, and both kidneys with the fat on them, and burn them on the altar.
Take all the fat that covers the entrails
In the sacrificial system, fat was considered the best part of the animal and was reserved for God. The entrails, or inner parts, symbolize the innermost being of a person, suggesting a complete offering to God. This act of taking the fat signifies giving God the best and most valuable parts, reflecting the principle of offering our best to God in worship and service.

and the lobe of the liver
The liver was seen as a vital organ, often associated with emotions and decision-making in ancient cultures. The specific mention of the liver's lobe highlights the thoroughness required in the sacrificial process. This detail underscores the importance of precision and obedience in following God's commands, reflecting the need for careful adherence to His instructions.

and both kidneys with the fat on them
In ancient Near Eastern thought, kidneys were considered the seat of emotion and conscience. Offering the kidneys with their fat signifies a surrender of one's innermost thoughts and feelings to God. This act can be seen as a type of Christ, who offered Himself wholly and without reservation, fulfilling the law's requirements perfectly.

and burn them on the altar
Burning the fat and organs on the altar represents the complete consumption of the offering by fire, symbolizing purification and the ascent of the offering to God. The altar serves as a place of atonement and reconciliation, pointing to the ultimate sacrifice of Jesus Christ, who offered Himself as a fragrant offering and sacrifice to God. This act of burning also connects to the idea of a pleasing aroma to the Lord, as seen in other sacrificial contexts throughout the Old Testament.
