The notion (from one verse) that King David will return in the flesh is put to bed immediately1 and repeatedly2 in the early days of the church. David’s body had “seen corruption”1,2. Jesus had risen without seeing bodily corruption1,2 and it was He that fulfilled the promise originally given to David3 by God and recalled by the prophets4,5,6,7,8,9,10 until “the last days.”
All of this requires the Bible student to consider the single phrase in Jeremiah 30 through a different lens. But then when considered with other statements from Jeremiah4,5 about David’s return, it’s clear that Jeremiah isn’t meaning a literal reincarnation of David in 30:9.
And if the additional prophets’ statements3,4,5,6,8,9 and inspired, New Testament writers’1,2,3,6,9,10 confirmations weren’t enough (and they are), we have the similar instance of Elijah. In this case the prophet Malachi said that Elijah would be raised, but multiple New Testament passages confirm this was not meant as a bodily raising of Elijah. Just like John the Baptist was to Elijah, Jesus was to David – “a man after my [God’s] heart, who will do all my will.” (Acts 13:22)
