NET
1 One dead fly makes the perfumer’s ointment give off a rancid stench, so a little folly can outweigh much wisdom.
Darby
1 Dead flies cause the ointment of the apothecary to stink [and] ferment; [so] a little folly is weightier than wisdom [and] honour.
KJV
1 Dead flies cause the ointment of the apothecary to send forth a stinking savour: [so doth] a little folly him that is in reputation for wisdom [and] honour.
