'Labourer' in the Bible

The appetite of the labourer laboureth for him, for his mouth urgeth him on.

The sleep of the labourer is sweet, whether he have eaten little or much; but the fulness of the rich doth not suffer him to sleep.

Have patience, therefore, brethren, till the coming of the Lord. Behold, the labourer awaits the precious fruit of the earth, having patience for it until it receive the early and the latter rain.
