Knavery may serve for a turn, but honesty is best in the long run.

Deceitful or unscrupulous conduct—“knavery,” an older-sounding term for such behavior—can sometimes produce an immediate advantage, especially when someone seeks a quick solution. The proverb warns that such gains are temporary and do not outweigh the enduring value of honest behavior.

It recommends judging conduct by its lasting consequences rather than by a single successful outcome. Honesty is presented as the wiser course because it is more likely to preserve trust, security, and sound results over time.

Use this proverb when contrasting a tempting dishonest shortcut with the longer-term benefits of acting truthfully and fairly. It suits advice or reflection on dealings where immediate profit may damage trust or create later harm.
