Isaac Watts - Against Evil Company

Why should I join with those in Play,
In whom I've no delight,
Who curse and swear, but never pray,
Who call ill Names, and fight.

I hate to hear a wanton Song,
Their Words offend my Ears:
I should not dare defile my Tongue
With Language such as theirs.

Away from Fools I'll turn my Eyes,
Nor with the Scoffers go;
I would be walking with the Wise,
That wiser I may grow.

From one rude Boy that's us'd to mock
Ten learn the wicked Jest;
One sickly Sheep infects the Flock,
And poysons all the rest.

Isaac Watts
