'Blows' in the Bible

Even to this hour we are without food, drink, and clothing, we are given blows and have no certain resting-place;

So then I am running, not uncertainly; so I am fighting, not as one who gives blows in the air:

But I give blows to my body, and keep it under control, for fear that, after having given the good news to others, I myself might not have God's approval.
