Which psalms did David write?
So we know David wrote the most of the psalms73 that were sure of.
These ones are his, specifically:
Psalms 3 9
Psalms 1141
Psalms 5165
Psalms 6870
Psalm 86
Psalm 101
Psalm 103
Psalms 108110
Psalm 122
Psalm 124
Psalm 131
Psalm 133
Psalms 138145
To be fair, the Septuagint (the Greek translation of the Old Testament) and the Latin Vulgate ascribe a few more psalms to David, which brings the count as high as 85.
Which psalms were not written by David?
The rest, of course! =)
