'Working' in the Bible

Homes we have none. Wearily we toil, working with our own hands. When reviled, we bless; when persecuted, we bear it patiently;

Or again, is it only Barnabas and myself who are not at liberty to give up working with our hands?

But what I am I am by the grace of God, and His grace bestowed upon me did not prove ineffectual. But I labored more strenuously than all the rest--yet it was not I, but God's grace working with me.
