to a citizen of that country
The mention of a "citizen of that country" underscores the son's alienation from his own people and heritage. In Jewish culture, associating with Gentiles was often seen as undesirable, and this detail highlights the depth of the son's estrangement. It also reflects the broader biblical theme of exile and separation from God, as seen in the experiences of Israel in the Old Testament.

who sent him into his fields
Being sent into the fields signifies a menial and degrading task, especially for someone of Jewish heritage. Fields were often associated with hard labor and servitude, contrasting sharply with the son's previous life of ease. This imagery is reminiscent of the Israelites' bondage in Egypt, serving as a metaphor for the bondage of sin.

to feed the pigs
Feeding pigs would have been particularly abhorrent to a Jewish audience, as pigs were considered unclean animals according to Levitical law (Leviticus 11:7). This task symbolizes the depth of the son's degradation and the spiritual impurity he has reached. It serves as a powerful illustration of the consequences of turning away from God and the depths to which sin can lead. The imagery of uncleanness also foreshadows the need for redemption and cleansing, themes central to the message of Jesus Christ.

- The younger son acts on his own decision, physically departing from his homeland (Luke 15:13).

- Scripture shows that stepping away from God-given provision brings trouble (Jonah 1:3; Proverbs 14:12).

- The action is literal: he truly “went,” distancing himself from his father’s household and its safety.

- He is no longer an heir but a hireling, exchanging sonship for servitude (Galatians 4:7; John 8:34).

- Leviticus 25:39 warns Israelites against selling themselves to strangers; his choice highlights desperate spiritual bankruptcy.

- The “citizen” is a Gentile resident of the far country (Ephesians 2:12), underscoring how far the son has strayed from covenant community.

- Psalm 1:1 cautions against close alliance with the ungodly; here the alliance is employment under them.

- Instead of hospitality, the employer dispatches him to labor—no special favor for a prodigal.

- Genesis 3:23 mirrors this exile to toil outside paradise; sin’s path often ends in harsher work, not freedom.

- Isaiah 55:2 asks, “Why spend your labor on what does not satisfy?” The fields yield no true fulfillment.

- Swine were ceremonially unclean (Leviticus 11:7). Caring for them places the son at the lowest social and spiritual rung.

- The detail is historical and literal; it communicates total degradation.

- 2 Peter 2:22 pictures sin’s filth with a pig wallowing in mire, showing how unrepentant choices soil one’s life.

- Mark 5:11-13 links pigs with demonic oppression, deepening the image of spiritual contamination.

Luke 15:15 portrays, step by step, the prodigal’s plunge from privileged son to humiliated swineherd. Each clause records a factual descent: departing, self-enslaving, leaving covenant community, working in exile, and wallowing in uncleanness. The verse warns that sin’s promises end in servitude, isolation, futile labor, and defilement—yet sets the stage for the Father’s redeeming grace that follows.

To a citizen.--Literally, to one of the citizens. In the outer story of the parable, this would emphasise the misery into which the man had fallen. The son of Abraham had to depend upon the bounty of an alien. In the two lines of interpretation, the "citizen" is one who all along has been of the world, worldly, living for no higher end than gain or pleasure. The prodigal is as one who, called to a higher life, has forfeited its blessedness, and now depends for such joy as he is capable of on those who are more completely identified with evil. It is, perhaps, natural that as we diverge more widely from the primary scope of the parable, its application in detail should become more difficult; and looking at the parable, as giving an outline of the history of the human race, one fails to see who answers to the "citizen." Not the Tempter, the great author of the world's evil, for the citizen is one of many. Nor is it the part of the citizen here to tempt to evil, but rather to be half-unconsciously God's instrument in punishing it--half-unconsciously, again, the means of preserving the evil-doer from perishing, and so of making a subsequent deliverance possible. It is truer to facts, therefore, to see in the "citizen" the representative of the wisdom and knowledge, maxims of worldly prudence or principles of ethics without religion, which for a time sustain the soul, and "still the hungry edge of appetite," and keep it from sinking utterly, while yet they leave it in its wretchedness and do not satisfy its cravings.

To feed swine.--We feel at once the shudder that would pass through the hearers of the parable as they listened to these words. Could there be for an Israelite a greater depth of debasement? In the inner teaching of the parable, this perhaps implies a state in which the man's will and energies have but the one work of ministering to his baser appetites. Such, in the long-run, is the outcome of the wisdom described in the previous note as answering to the "citizen."
