9:1 The verb translated praise is translated “thank” in 7:17, suggesting a close connection between Pss 7 and 9 (see 7:17; 8:1-2). With all my heart expresses the psalmist’s deep devotion and commitment (86:12; 111:1; 119:10; 138:1). • I will tell: These stories educate the next generation (78:4; 145:4); when they are not remembered, a generation might easily depart from the Lord (78:11, 32). • The marvelous things include the Lord’s judgments on the enemies of his people (9:4) and his care for the oppressed (9:9). The wonders in creation, in redemption, and in revelation reveal his character and show his power (89:5; 111:4; 119:18, 27). His powerful manifestations evoke public praise (9:1; 26:7; 75:1).

Pss 9–10 This hymn celebrates the Lord’s kingship and victory over evil. It might also serve as a response to the laments of Pss 3–7. Some believe that Pss 9 and 10 should be read together as one psalm in two parts because Ps 9 includes a title and Ps 10 does not, and although several letters are missing or inverted, the two psalms connect as an acrostic of the Hebrew alphabet (other such alphabetic acrostics are Pss 25, 34, 37, 111–112, 119, 145). The ancient Greek and Latin translations treat 9 and 10 as one.
