In Acts 1:20 we read: > "For it is written in the Book of Psalms: > > > ‘Let his encampment become desolate, and may no one dwell in it.’ > > And: > > > ‘May another take his office.’" But Psalm 69:26 is actually uses plural: > "Make their camp desolate, with none to dwell in their tents." Psalm 109:8 has singular: > "May his days be few; may another take his office." (All translations can be found from the [USCCB website](https://bible.usccb.org/bible).) So it seems to me that St. Peter is changing the plural of Psalm 69:26 into singular in order to make a point. Then he quotes Psalm 109:8 in order to make a point. He seems to be just picking Psalm texts or changing the plural into singular in order to make a point. This is just confusing. I have been searching commentaries on this but have not been able to found one. This could be because people just take for granted that changing the plural into singular is a natural thing that people can just do. **What is going on in Acts 1:20?**

As I read the gospels and the other NT books, both Jesus and the authors all seem to take the OT as entirely historically accurate, especially the events of Genesis and Exodus. Additionally, this assumption of the literal accuracy of the OT appears to not just be a side note, but form the core of many of their theological arguments. Is this a correct impression of Jesus and the NT authors? I found one question that seems to support this interpretation of Jesus' perspective, at least to a degree.
