Isaiah 38:2

“Then Hezekiah turned his face to the wall, &c.] Not figuratively to the wall of his heart, as Jerom; but literally, either to the wall of his bedchamber where he lay sick, that his tears might not be seen, and his prayers interrupted, and that he might deliver them with more privacy, freedom, and fervency; or else to the wall of the temple, as the Targum, towards which good men used to look when they prayed, (<110838>1 Kings 8:38 <270610> Daniel 6:10), which was a type of Christ, to whom we should have respect in all our petitions, as being the only Mediator between God and man: and prayed unto the Lord; as follows:”

Hezekiah probably turned his face to the wall in order that his emotion and his tears might not be seen by the bystanders, or in order that he might compose himself the better for devotion. His prayer he wished, doubtless, to be as secret as possible. The Chaldee renders this, ‘Turned his face to the wall of the house of the sanctuary;’ that is, of the temple, so that it might appear that…”

“turned: Hezekiah's couch was probably placed in a corner, which is the place of honour in the East; in which, turning on either side, he must turn his face to the wall; by which he would withdraw himself from those attending him in his apartment. Kg1 8:30; Psa 50:15, Psa 91:15; Mat 6:6 Isaiah 38:3”
