Dark is he whose eye's not single;

Dark is he whose eye's not single;
Foolish man never can
Hell with heaven mingle.

Everything we do we sin in.
Chosen Jews must not use
Woollen mixed with linen.

God is holy in his nature;
And by that needs must hate
Sin in every creature.

Infinite in truth and justice,
He surveys all our ways;
Knows in whom our trust is.

Partial service is his loathing;
He requires pure desires;
All the heart, or nothing.

If we think of reconciling
Black with white, dark with light,
'Tis but self-beguiling.

Righteousness to full perfection
Must be brought, lacking nought,
Fearless of rejection.
