A Threefold Cord

Two are better than one,
because they have a good return for their labor.
For if one falls down,
their companion can lift them up;
but pity the one who falls
without another to help them up!

Again, if two lie down together,
they will keep warm;
but how can one keep warm alone?
And though one may be overpowered,
two can resist.
Moreover, a cord of three strands
is not quickly broken.

–Ecclesiastes 4:9-12
