day of the Lord
1 Thessalonians 5:2
5:2 day of the Lord. This is the first written mention of “the day of the Lord” in the New Testament, although Peter had quoted the phrase from the Old Testament (Joel 2:31) in his sermon on the day of Pentecost (Acts 2:20). This phrase is used over thirty times in the Old Testament. In context here, it refers to the coming of the final period of God’s judgment on the earth.
