'Two' in the Bible

One hand full of rest is better than two fists full of labor and striving after wind.

Two are better than one because they have a good return for their labor.

Furthermore, if two lie down together they keep warm, but how can one be warm alone?

And if one can overpower him who is alone, two can resist him. A cord of three strands is not quickly torn apart.

Sow your seed in the morning and do not be idle in the evening, for you do not know whether morning or evening sowing will succeed, or whether both of them alike will be good.
