New Defender's Study Bible Notes
6:1 return unto the LORD. Following God’s pronouncement in the preceding verse that He is awaiting Israel’s confession and repentance, the prophet puts himself in the place of returning Israel in the last days, prophetically anticipating her confession and resultant restoration.
6:2 the third day. Two prophetic mysteries are suggested here. Jesus Christ, representing the true Israel in His death, was raised the third day. The earthly nation of Israel, seemingly “dead” for about two thousand years, will be raised for her thousand-year millennial reign, when she returns to Messiah, and He to her at the end of this present age (Ezekiel 37:12-14). On the divine equation that “one day is with the Lord as a thousand years,” see the note on II Peter 3:8.
6:6 mercy, and not sacrifice. The Lord Jesus quoted this verse in Matthew 9:13, affirming the eternal principle that religious rituals were meaningless without the obedience in heart and life that they were supposed to express.
