I. (9:1–2) The Worshiper’s Intent to Give Thanks. The psalm opens with the singer’s desire to thank God for his “wonderful deeds,” which here would refer to the deeds in the following verses that show God’s care, both for particular persons and for his whole people.

Each member of the congregation aims to give thanks “with [his or her] whole heart” (v. 1). The biblical ideal is for the whole inner self to be engaged in loving and praising God (Deut. 6:5), whether in private or in public (as here). The goal of singing this is for the members to admire and aspire to such earnestness.

II. (9:3–6) The Enemies Have Fallen. The psalm begins to recount the particular wonderful deeds in view, namely, the downfall of the singers’ enemies. These verses envision a successful campaign to protect God’s people and their king from some evil scheme of Gentile powers to oppress them; the victory is a decisive one (Ps. 9:5–6). When an Israelite sings of “my just cause” (v. 4), he should think beyond the simple right to live unmolested by foreigners to the very purpose of the call of Israel, namely, to be a light to the Gentiles through living faithfully in the covenant (v. 11 alludes to this purpose).

The song addresses the God who has “sat on the throne” (v. 4, also v. 7; for similar terms cf. 29:10; 47:8; Isa. 6:1). God on his throne dispenses “righteous judgment,” protecting the weak against predation by the strong. Although the focus here is on God’s own people, his rule and judgment extends to all the “peoples” of the world (Ps. 9:8).

III. (9:7–10) The Lord’s Just Rule Is His People’s Security. In this next section the singer celebrates how the Lord’s righteous rule provides security for his people. To speak of God’s “throne” (v. 7) is to remember his awesome might; to speak of “justice,” “righteousness,” and “uprightness” (vv. 7–8) is to remember the good and holy ends for which God wields his might, namely, to protect those who know his name (v. 10) and to achieve his purpose of bringing light to the benighted world.

The terms “sits” and “throne” (v. 7) echo the idea of verse 4, as does the concern with “justice” and “righteousness” (v. 8).

That Israel’s God “judges the world” and all its “peoples” (v. 8) would be a bold claim were it not that he is the same God who made heaven and earth and all that is in them. In this particular case the judging is punitive, but, as indicated above (cf. comment on 9:3–6), this need not be true in every case and at all times; see, for example, Isaiah 2:4, where God’s judging describes his just rule over the Gentiles in the coming era. This psalm is suited for a time in which God’s judgment has vindicated “the oppressed” (Ps. 9:9), the people of Israel seen as weak and needy, while the Gentile rulers sought to oppress them.

The stanza ends with an affirmation of faith: to “know” God’s “name,” to “put . . . trust in” him, and to “seek” him are all ideals of OT piety, of which the members of Israel often fell short. But those who sing this are here enabled to refresh their yearning to be true to this ideal.

IV. (9:11–12) A Call for God’s Faithful to Sing His Praises. The singer urges the people of God to make his praises known to the world.

In verse 11 the singers invite one another to “tell among the peoples his deeds” (cf. Isa. 12:4; Ps. 105:1 for a similar expression and Pss. 18:49; 96:3 for the idea). God called Abraham and Israel for the sake of the whole world, and one function of passages like these is to cultivate in Israel a yearning for the time at which the Gentiles would receive the blessing; Paul cites a number of texts to this effect in Romans 15:8–12 in order that the Roman Christians might see that such a time has now come.

In Psalm 9:12 God is “mindful of them,” namely, the oppressed people of Israel (v. 9), whose “blood” he “avenges” when the Gentiles would spill it unjustly. This serves to reassure God’s people that it is worthwhile to maintain their faithfulness to him, even when it may cost them suffering at the hands of those who oppose God’s purposes.

V. (9:13–14) A Prayer for Relief. In these verses the song moves to a prayer for deliverance from affliction. The previous threat (vv. 3–6) makes it clear that others are yet to come, while the decisive victory has displayed God’s commitment to protect and preserve his people. These coming threats are deadly (v. 13), and the result of God’s answer to the prayer will be further praise in worship (v. 14; cf. vv. 1–2).

In the context of this psalm, “those who hate me” (v. 13) refers not to one’s personal enemies but rather to those who hate the singer because of his membership in God’s people; that is, they “hate me” because they oppose my God (similarly, John 15:18–25).

VI. (9:15–18) God Protects the Needy by Defeating the Wicked. The song again celebrates how God defends the poor by defeating their oppressors. Here “the wicked” (Ps. 9:16, 17) are expressly those Gentiles who oppose God’s purposes (vv. 15, 17), while the “needy” and “poor” (v. 18) are the people of Israel under threat.

On “Sheol” (v. 17), see the comment on 6:1–5. Here it refers to a destination of the wicked, not of God’s faithful, as it does in, for example, 49:14–15 (cf. comment on 49:13–20). The “nations,” those Gentiles carrying out the oppression, are said to “forget God”; on the other hand, “the needy shall not always be forgotten” by him.

VII. (9:19–20) Prayer for God to Judge the Nations. The song prays for God to “arise” (as in 3:7; 7:6; 10:12; 17:13; cf. Num. 10:35), to make his protection of the faithful visible to all (as the second line, “let the nations be judged before you,” makes plain). By referring to these Gentiles as “man” in Psalm 9:19 and “men” in verse 20 (both ʼenosh, a poetic word for human beings; as in 8:4), the song contrasts the pretensions of their schemes with the just and good plan of the all-ruling God himself.
