1 Kings 8:38 - Joseph Benson’s Commentary on the Old and New Testaments

What prayer and supplication soever be made by any man Distressed through national calamities, or private and personal troubles. He now comes to speak of the case of individual Israelites. If any man of Israel has an errand to thee, here let him find thee, here let him find favour with thee. He does not instance in particulars; so numerous, so various are the grievances of the children of men. Which shall know every man the plague of his own heart His sinfulness, the corruption of his nature, which may be called the plague of his own heart, in opposition to the other plagues here mentioned: and so the sense is, Who by their afflictions are brought to a true and serious sense of the inward plague of their sins, which are most fitly called the plague of the heart, because the heart is both the principal seat of sin, and the fountain from whence all sinful thoughts, words, and actions flow. Now every true Israelite labours to know his heart, and the sinfulness and depravity of it, that he may resist and mortify the lusts, passions, and corrupt inclinations thereof, and may watch against the first risings of evil within him. Of these things he complains: these drive him to his knees and to the sanctuary, and, lamenting and seeking deliverance from these, he spreads forth his hands in prayer, as Hezekiah spread his letter before the Lord. Reader, is this thy practice?
