Leviticus 25:10
8 “‘You must count off seven weeks of years, seven times seven years, and the days of the seven weeks of years will amount to 49 years. 9 You must sound loud horn blasts—in the seventh month, on the tenth day of the month, on the Day of Atonement—you must sound the horn in your entire land. 10 So you must consecrate the fiftieth year, and you must proclaim a release in the land for all its inhabitants. That year will be your Jubilee; each one of you must return to his property, and each one of you must return to his clan. 11 That fiftieth year will be your Jubilee; you must not sow the land, harvest its aftergrowth, or pick the grapes of its unpruned vines. 12 Because that year is a Jubilee, it will be holy to you—you may eat its produce from the field.
Isaiah 61:2
1 The Spirit of the Sovereign Lord is upon me, because the Lord has chosen me. He has commissioned me to encourage the poor, to help the brokenhearted, to decree the release of captives and the freeing of prisoners, 2 to announce the year when the Lord will show his favor, the day when our God will seek vengeance, to console all who mourn, 3 to strengthen those who mourn in Zion by giving them a turban, instead of ashes, oil symbolizing joy, instead of mourning, a garment symbolizing praise, instead of discouragement. They will be called oaks of righteousness, trees planted by the Lord to reveal his splendor. 4 They will rebuild the perpetual ruins and restore the places that were desolate; they will reestablish the ruined cities, the places that have been desolate since ancient times.
Notes and References
"... Isaiah 61:1-11 ... The appearance of one anointed by the Lord, on whom the spirit of the Lord rests, recalls references to the Davidic messiah (Isaiah 11:2), the Servant of the Lord (Isaiah 42:1–4) and even Cyrus (Isaiah 45:1). Butt most assume it is the prophet himself speaking, like Micah who claimed he was ‘filled with the spirit of Yahweh’ (Micah 3:8). ‘Anointing’ is rarely used of prophets (1 Kings 19:16; Psalm 105:15), and it may be used here in a nontechnical sense, a synonym for ‘send’ or ‘appoint’, or ‘nothing but an expression of nobility and greatness’. ‘Bringing good news’ is already familiar (Isaiah 40:9; 41:27; 52:7) and the ‘year of the Lord’s favor’ recalls the ‘day of the Lord’s favor’ (Isaiah 49:8; 58:5), but ‘binding up the brokenhearted’ and ‘proclaiming liberty to the captives’ appear only here in Isaiah and make this passage strikingly original and much quoted. The word ‘liberty’ (Hebrew 'deror') from the law of the Jubilee (Leviticus 25:10) occurs only here and in Jeremiah 34:8, 15, 17 ..."
