'Labour' in the Bible

six days thou dost labour, and hast done all thy work,

and we cry unto Jehovah, God of our fathers, and Jehovah heareth our voice, and seeth our affliction, and our labour, and our oppression;

The fruit of thy ground, and all thy labour, eat up doth a people whom thou hast not known; and thou hast been only oppressed and bruised all the days;
