3:5 children of Israel return. After these “many days,” during which the “times of the Gentiles” (Luke 21:24) run their course, and “the fulness of the Gentiles” (Romans 11:25) is “[taken] out of them [as] a people for His name” (Acts 15:14), then the children of Israel will return to seek the Lord in the latter days.
3:5 David their king. Not only will they seek God as they had known Him in ancient times, but also will acknowledge “David” as their king. That is, they will recognize Jesus as the long-awaited “son of David,” who was also the Son of God whose “throne shall be established for ever” (II Samuel 7:12-16; Luke 1:31-33; Matthew 22:41-45). In a secondary application, it may also be that David himself, resurrected with all Old Testament saints, will again rule over earthly Israel during the millennium, when the apostles also will be “judging the twelve tribes of Israel” (note Matthew 19:28; 27:52-53; I Corinthians 6:2; Revelation 20:4; Jeremiah 30:9; Ezekiel 34:23-24).
