King James Bible
"He that laboureth laboureth for himself; for his mouth craveth it of him."
The repetition of 'laboureth' emphasizes that work is fundamentally self-directed—people toil primarily to meet their own needs. This observation from Hebrew wisdom literature acknowledges the natural, God-given drive for self-preservation through honest work. Physical hunger serves as the primary motivator for labor, with 'mouth' representing basic bodily needs. The verb 'craveth' suggests an urgent, compelling force that drives a person to work, illustrating how God uses natural appetites to encourage diligence and productivity.
