But they shall serve the LORD their God, and David their king, whom I will raise up unto them. But they shall serve the Lord their God, and David their King - This must refer to the times of the Messiah and hence the Chaldee has, "They shall obey the Lord their God, וישת מאון למשיחה בר דוד veyishta meun limschicha bar David, and they shall obey the Messiah, the Son of David." This is a very remarkable version; and shows that it was a version, not according to the letter, but according to their doctrine and their expectation. David was long since dead; and none of his descendants ever reigned over them after the Babylonish captivity, nor have they since been a regal nation. Zerubbabel, under the Persians, and the Asmoneans, can be no exception to this. They have been no nation since; they are no nation now; and it is only in the latter days that they can expect to be a nation, and that must be a Christian nation.
