This hymn celebrates the Lord's rule and triumph over evil. It may also respond to the laments in Psalms 3–7.
Some believe that Psalms 9 and 10 should be read together as one psalm in two parts. This is because Psalm 9 has a title, while Psalm 10 does not.
Despite some missing or inverted letters, the two psalms form an acrostic of the Hebrew alphabet. This means that each line or section begins with a successive letter of the Hebrew alphabet.
Other alphabetic acrostics include Psalms 25, 34, 37, 111–112, 119, and 145.
The ancient Greek and Latin translations treat Psalms 9 and 10 as one psalm.
