Proverbs 6:9-11 says:
How long will you lie there, you sluggard?
When will you get up from your sleep?
A little sleep, a little slumber,
a little folding of the hands to rest-
and poverty will come on you like a bandit
and scarcity like an armed man.
Being slothful not only applies to work, but to other areas. Like balancing your checkbook, or living on a budget.
