Psalm 9:1

• The verb translated as give thanks is also translated as thank in Psalm 7:17. This shows a strong connection between Psalms 7 and 9 (see 7:17; 8:1–2).

  The phrase with all my heart shows the psalmist’s deep devotion and commitment (Psalms 86:12; 111:1; 119:10; 138:1).

• I will recount: These stories teach the next generation (Psalms 78:4; 145:4). If forgotten, a generation might easily turn away from the Lord (Psalms 78:11, 32).

• Your wonders: These include the Lord’s judgments on the enemies of his people (Psalm 9:4) and his care for the oppressed (9:9). The wonders in creation, redemption, and revelation show his character and power (Psalms 89:5; 111:4; 119:18, 27). His powerful acts inspire public praise (Psalm 9:1; 26:7; 75:1).

However, that tune (or song) is no longer known. The same is true for the tunes mentioned in Psalms 22, 45, 56–60, 69, 75, and 80.

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.
