2.236

知足不辱。知止不殆（殆危也。可行可止。則不危其身。故曰知足不辱。漢疏廣曰。賢而多財則損其志。愚而多財則益其過。故曰知止不殆）。

Knowing contentment, one incurs no disgrace; knowing when to stop, one faces no danger; (['Danger':] dai means perilous. When one knows when to act and when to stop, one will not endanger one's body; hence it says 'knowing contentment, one incurs no disgrace.' Shu Guang of the Han said: 'If the worthy has much wealth, it impairs his aspiration; if the foolish has much wealth, it increases his faults.' Hence it says 'knowing when to stop, one faces no danger.')
