Why: but that sacrifice performed for the sake of some benefit, or for the sake of show, know that to be of passion, again naming performative, self-interested motivation as the marker of the restless quality even when the outward act appears identical.

In life: performing a generous act primarily for show, for social recognition or personal gain, is a specific, recognizable pattern worth catching directly in yourself rather than mistaking for genuine generosity simply because the outward act looks the same.

Teaching: the next time you catch yourself performing a generous or dutiful act primarily for how it will look to others, name that motivation directly, this verse treats it as a meaningfully different act than genuine, unperformed generosity, even though the outward form is identical.
