This is illustrated in the account of Jonah and the warnings God gave to David—warnings that did not come to pass, not because God alters His decree, but to draw humanity closer to Himself. For He is the Lord, who relents from bringing calamity (2 Chronicles 36:28, Prayer of Manasseh v. 6, Joel 2:13, Jonah 4:2).
Hezekiah faced the wall because he could not go to the temple. This wall was likely near the temple where Solomon built a palace, serving as a private space for his tears, or perhaps, as suggested by Jeremiah's reference to the heart as a 'wall,' it signified his deepest thoughts, where he could earnestly plead with the Lord. He exclaimed, "Remember, O Lord, I beg You, how I have walked before You in faithfulness and with a whole heart, and have done good in Your sight." Upon learning he was to die, he did not implore for numerous years of life, but accepted God's judgment, recognizing that Solomon pleased God in his request for wisdom instead of long life. He brought forth his deeds, asserting his faithfulness before God. Truly, blessed is the conscience that recalls its good works in times of trial, for blessed are the pure in heart, for they shall see God (Matt. 5:8). Moreover, it is stated: "Who can claim to have a pure heart?" (Proverbs 20:9). This indicates that Hezekiah was considered pure of heart for his demolishing of idols, destroying the vessels of Baal’s temple, and breaking the bronze serpent among other righteous acts documented in Scripture (4 Sam. 18:3-5, 2 Ch. 29-31).
He wept abundantly over the promise made to David, perceiving it as threatened by the impending death of his son, Hezekiah, since he had no heirs at the time, and following his death, Manasseh, just twelve years old, took the throne in Judah (2 Chronicles 33:1). This implies that Manasseh was born after Hezekiah's life was extended. Thus, Hezekiah's lament was rooted in the fear of losing the lineage from which Christ would come. Some argue that the most devout fear death due to the uncertainties surrounding God’s judgment and the fate they may face thereafter. The matters of fate and necessity are not predetermined for all, but hinge upon God's will for reasons known only to Him, leading to life or death. Especially as we recognize that many have been raised from the dead after their demise.
