A frequent misinterpretation portrays Saul's reasoning as pious observance of Mosaic law or merciful understanding toward David's supposed impurity, overlooking that it serves as self-delusion to suppress emerging jealousy and paranoia toward David, rather than true spiritual discernment or leniency, thus missing the narrative's buildup to Saul's hostility.
I Samuel 20:26
King James Version (1769)
26 Nevertheless Saul spake not any thing that day: for he thought, Something hath befallen him, he is not clean; surely he is not clean.
In this verse, Saul excuses David's absence from the royal feast by assuming he is ritually unclean, reflecting the king's initial rationalization that delays suspicion and buys David time amid growing tensions, while highlighting ancient Israelite customs of ceremonial purity that prohibited participation in sacred meals by the unclean.
