Allusion2
A deliberate verbal borrowing without a citation formula.
'A little yeast leavens the whole lump... purge out the old yeast' draws directly on the Passover command to 'put away leaven out of your houses,' on pain of being 'cut off from Israel.' High Volume and Coherence: Paul reads the literal de-leavening as figural for purging the immoral man, and the cutting-off sanction matches 5:13.
High confidence'A little yeast leavens the whole lump' draws on the Passover/Unleavened Bread command to purge all leaven from the house, where leaven functions as a spreading defilement. Volume and availability are high; the agricultural proverb is freighted with the cultic logic of total removal that fits Paul's warning about the agitators.
High confidenceEcho1
A fainter, low-volume reuse, carried by recurrence or thematic coherence.
The warning against 'the yeast/leaven of the Pharisees and Sadducees' trades on the Passover/Unleavened Bread association of leaven with pervasive corruption that must be purged from the house. The metaphor's intelligibility presupposes this cultic background.
