The Greek word siteutós, represented by G4618, means grain-fed, i.e. fattened. This term appears 3 times across 3 unique verses in the Bible, and is used to describe an animal specially prepared for a significant feast.
In its biblical usage, G4618 is found exclusively within the Parable of the Prodigal Son in Luke's Gospel. It is always used in the phrase "the fatted calf." This signifies an extravagant celebration prepared by the father upon the return of his lost son. The father commands, "bring hither the fatted calf, and kill it; and let us eat, and be merry" Luke 15:23. The term is later used in the complaint of the older brother, who notes that the father has killed the "fatted calf" for the son who had "devoured thy living with harlots" Luke 15:30.
Several related words help illustrate the context of this celebratory welcome:
- G3448 móschos (calf): This word specifies the animal being prepared. It is defined as a young bullock and is the object prepared for the feast (Luke 15:23, Luke 15:27, Luke 15:30). Its use is also seen in descriptions of sacrifices Hebrews 9:19.
- G2380 thýō (kill): This verb, meaning to sacrifice or slay, describes the action taken with the fatted calf. The father commands the servants to kill it for the feast Luke 15:23, an action later recounted by the servant and the older son (Luke 15:27, Luke 15:30).
- G2165 euphraínō (be merry): This word captures the purpose of preparing the fatted calf. It means to rejoice or be in a good frame of mind. The father's intent is for everyone to eat and be merry Luke 15:23, and he later affirms that it was necessary to make merry because the lost son had been found Luke 15:32.
- G3962 patḗr (father): This word identifies the one who calls for the celebration. As a term for father, it denotes the source of the extravagant welcome and forgiveness, who rejoices at receiving his son "safe and sound" Luke 15:27.
The theological significance of G4618 is concentrated in its single narrative context:
- Symbol of Extravagant Welcome: The fatted calf was not an ordinary meal but was reserved for a special occasion. Its preparation shows the immense joy and high value the father places on the son who was lost but is now found Luke 15:27.
- Sign of Full Restoration: The feast centered around the fatted calf marks the son's complete reinstatement into the family. The celebration signifies that the son, who was "dead, and is alive again," is fully restored to his position Luke 15:32.
- Illustration of Unmerited Grace: The older brother's grievance highlights the calf's significance. He contrasts his own faithfulness with his brother's sin, yet the father provides the fatted calf for the penitent sinner, symbolizing a grace that is not earned but given freely Luke 15:30.
In summary, while siteutós G4618 is a rare word, its singular context makes it deeply significant. As the "fatted" calf, it transforms from a simple agricultural term into a powerful symbol of joyous celebration, radical forgiveness, and the lavish, unearned welcome that awaits the repentant. It memorably illustrates the heart of a father who rejoices over the restoration of his child.
