2 Kings 20:2 - Joseph Benson’s Commentary on the Old and New Testaments

Then he turned his face to the wall As he lay in his bed. He could not retire to his closet; but he retired as well as he could; he turned from the company to converse with God. When we cannot be so private as we would in our devotions, nor perform them with the usual outward expressions of reverence and solemnity, yet we must not, therefore, omit them, but compose and address ourselves to them as well as we can.
