Psalms 86:15
What does Psalms 86:15 mean?
But you, Lord, are a merciful and gracious God, slow to anger, and abundant in loving kindness and truth.
The short answer
Psalm 86:15 sounds like a burst of praise, but it is actually a quotation. When the psalmist prays, "But you, Lord, are a merciful and gracious God, slow to anger, and abundant in loving kindness and truth," he is repeating, almost word for word, what God said about himself to Moses on Mount Sinai in Exodus 34:6. This is not the psalmist's opinion of God; it is God's own self-description, prayed back to him.
Each word in the formula carries weight. The Hebrew behind "merciful" (raḥûm) shares a root with the word for womb, suggesting the visceral, protective tenderness of a mother for her child. "Gracious" (ḥanûn) describes God's freely given favor toward those who cannot earn it. "Slow to anger" translates a vivid Hebrew idiom that pictures patience as taking a long, deep breath—God does not have a short fuse. And "loving kindness" is the rich Hebrew word ḥesed, which names steady covenant loyalty rather than a passing warm feeling. Paired with "truth," it describes a love that keeps its promises.
What makes this verse remarkable is how often the same four-part cluster appears across the Old Testament—in Nehemiah 9:17, Psalm 103:8, Psalm 145:8, Joel 2:13, and Jonah 4:2. Israel treated these words as a kind of creed, a fixed confession of who God is. So when the psalmist, surrounded by enemies and pleading for help, reaches for this language, he is doing something bold: he is holding God to God's own word. The prayer's confidence rests not on how the psalmist feels in the moment, but on what God has already revealed about his character.
What scholars say
Both scholars trace the language of Psalm 86:15 back to God's self-declaration in Exodus 34:6, showing how this four-part description of God recurs as a fixed formula across the Old Testament—and Limburg opens up the tender Hebrew wordplay behind "merciful."
““Return to the L ORD ,” he says, because of what God is like: “gracious and merciful, slow to anger, and abounding in steadfast love, and repent(ing) of evil.” This is well-worn, traditional language that would be familiar to Joel’s hearers (cf. Exod. 34:6; Jonah 4:2). “Gracious and merciful” is a frequent pairing in the Psalms (111:4; 112:4; 145:8). The Hebrew root behind “merciful” is related to the word for womb; the sense seems to be “motherly love” (see the comments on “compassion” in Micah 7:19). “Slow to anger” is a human virtue (Prov. 14:29; 15:18; 16:32), but is most often used of the Lord (Neh. 9:17; Pss. 86:15; 103:8; 145:8). “Steadfast love” is the Hebrew hesed; see the comments on Hosea 6:6.”
“The allusion to Yahweh's self-declaration in Exod 34:6 contains four elements that appear elsewhere when Exod 34:6 is taken up formulaically (see Neh 9:17; Pss 86:15; 103:8; 145:8). This lexical cluster includes the terms ḥanûn (gracious), raḥûm (compassionate), ʾerek ʾapayim (slow to anger), and rab ḥesed (abundantly kind). The phrase relent concerning evil does not appear in Exod 34:6–7, but it does appear in Jonah 3:10 when recounting Yahweh's decision to withdraw punishment against the Ninevites (God relented concerning the evil that he had said he would do to them). Hence, the citation of Exod 34:6 in Jonah 4:2 incorporates the context of Jonah, but there is more. Joel 2:13 also contains the four elements that appear elsewhere, but it shares several features with Jonah 4:2 (that do not appear in Exod 34:6).”
What it means for you
This verse models a way of praying that many believers find steadying: praying Scripture back to God. When you are anxious, wronged, or simply worn down, you do not have to manufacture confidence or wait for the right feelings. You can do what the psalmist did—remind God, and yourself, of what God has said about his own character. "You are merciful and gracious, slow to anger, abundant in loving kindness."
Grounding prayer in God's self-revelation shifts the weight off your emotional state and onto something fixed. On days when God feels distant, this verse gives you words that were true before you felt anything at all—and will still be true after.
Psalms 86 in context
Psalm 86 is a prayer of David in a time of real trouble. He describes himself as "poor and needy" (v. 1) and tells God that proud, violent men have risen against him (v. 14). The whole psalm alternates between urgent petitions—hear me, preserve me, be merciful—and statements about who God is. Verse 15 comes at the turning point: right after naming his enemies, David pivots with "But you, Lord," setting God's revealed character against his circumstances. The appeal for help in verse 16 flows directly out of this confession.
