Psalms 108

The text moves from an internal state of worship ('my heart is fixed') to external declarations of God's sovereignty over the nations, culminating in a humble admission of human helplessness.

• God hath spoken in his holiness; I will rejoice, I will divide Shechem, and mete out the valley of Succoth (v. 7).
• Through God we shall do valiantly (v. 13).

• Awake, psaltery and harp: I myself will awake early (v. 2).

• Vain is the help of man (v. 12).

• The psalm serves as a national petition, likely utilized during a time of crisis where the people of Israel needed to invoke God’s prior promises of land and victory.
• The geographic references (Shechem, Gilead, etc.) reflect the historical borders established under the Davidic covenant.

• Casting the shoe over Edom (v. 9) is an ancient cultural act signifying the taking of possession or subjugation of a territory.
• The use of the harp (kinnor) and lyre (nebel) highlights the role of music in both personal and temple worship.

• It is an 'orphan' or composite psalm. By incorporating Ps 57:7-11 and Ps 60:5-12, the compiler demonstrates that the Word of God is 'living and active,' applicable across different historical moments.
• Matthew Henry observes that we may usefully select passages from different psalms to enliven our devotions, noting that the combination here helps the believer move from personal praise to corporate petition.

• The psalm highlights the canonical principle of Scripture interpreting Scripture. It takes earlier declarations of God's faithfulness (from Psalms 57 and 60) and applies them to a new context, showing that God's past actions are the basis for future hope.
• The reliance on God's 'right hand' (v. 6) mirrors Exodus 15:6 and other songs of victory, grounding the present need in the established biblical theology of God as the Warrior-King of His people.

• Psalm 108:1-5 is a quotation/adaptation of Psalm 57:7-11.
• Psalm 108:6-13 is a quotation/adaptation of Psalm 60:5-12.

• Steadfast (כּוּן [H3559]): Literally 'to be erect' or 'to stand perpendicular.' It describes a heart that is unwavering and firmly fixed on God.
• Steadfast love (חֵסֵד [H2617]): This is the fundamental covenant term for God's loyal, committed kindness toward His people.
• Faithfulness (אֶמֶת [H571]): Derived from a root meaning firmness or certainty; it signifies that God's word is entirely reliable.
• Answer (עָנָה [H6030]): To eye, heed, or respond; in this context, it is a plea for God to pay attention to His people's plight.

• The clear shift from the 'I' (the psalmist) in the first half to the 'We' (the nation/God's people) in the second half, demonstrating that personal, 'fixed' worship prepares the believer to pray for the broader community.
• The explicit confession in verse 12 that human help is 'vain' (or empty) serves as the theological pivot point upon which the final victory rests.

• There is no scholarly consensus on whether this composite psalm was compiled by David himself or by a later collector for a specific post-exilic crisis; both views are held by conservative scholars based on the evidence provided in the text itself.
• Theological debates persist over how to interpret the imprecatory and nationalistic elements (e.g., v. 9) in relation to the New Testament teaching on enemies; some see this as a literal prophecy of territorial judgment, while others interpret it as a typological shadow of the spiritual victory of Christ.
