'Breast' in the Bible

But the publican, standing afar off, would not lift up so much as his eyes unto heaven, but smote his breast, saying, God, be thou merciful to me a sinner.

He leaning back, as he was, on Jesus breast saith unto him, Lord, who is it?

Peter, turning about, seeth the disciple whom Jesus loved following; who also leaned back on his breast at the supper, and said, Lord, who is he that betrayeth thee?

And it was given unto him to give breath to it, even to the image to the breast, that the image of the beast should both speak, and cause that as many as should not worship the image of the beast should be killed.
