Psalm 25
1. Augustine’s Exposition on Psalm 25 (Full Sermon)
The most substantial item in the corpus is St. Augustine’s complete exposition on Psalm 25 from his Expositions on the Book of Psalms:
“PSALM XXV. TO THE END, A PSALM OF DAVID HIMSELF. Christ speaks, but in the person of the Church: for what is said has reference rather to the Christian People turned unto God. ‘Unto Thee, O Lord, have I lift up my soul’ (ver. 1): with spiritual longing have I lift up the soul, that was trodden down on the earth with carnal longings. ‘O my God, in Thee I trust, I shall not be ashamed’ (ver. 2). O my God, from trusting in myself I was brought even to this weakness of the flesh…”
This is a verse-by-verse patristic homily interpreting the Psalm Christologically, reading Christ as speaking in the voice of the Church. It continues across multiple pages in the NPNF collection.
2. Jewish Liturgical Prayer (Siddur) — Tahanun
In the Morning and Afternoon Services, the Tahanun (supplication) incorporates the language and themes of Psalm 25:6. The prayer reads:
“Remember thy mercy and thy kindness, O Lord, for they are eternal. May thy kindness rest on us, O Lord, as our hope rests on thee. O mind not our former iniquities…”
The footnote explicitly cites Psalm 25:6 among other scriptural sources .
3. Siddur — Musaf Service
The Musaf for festivals incorporates verses from Psalm 25. The prayer “Towards thee I direct my desire” (Psalm 25:1) and “Turn to me and be gracious to me, for I am lonely and afflicted” (Psalm 25:16) are woven into the liturgy, with footnotes citing both verses .
4. Breslov System of Learning
Quotes Psalm 25 as a proof-text for God’s goodness:
“G-d is only good, as is said, (Psalms 25), ‘Good and upright is G-d.'”
5. Sefer HaBahir (Kabbalah)
Cites Psalm 25:21 (“Complete and upright”) in a mystical discussion equating uprightness with peace and Torah truth .
Psalm 121
1. Siddur — Afternoon Service for Sabbaths (Full Psalm + Commentary)
The full text of Psalm 121 is recited, preceded by the editor’s note:
“Psalm 121 is a perfect expression of trust in God, and has been on the lips of countless people when they felt the need of help beyond that which mortals can offer.”
The text: “A Pilgrim Song. I lift my eyes to the hills; whence will my help come? My help comes from the Lord who made heaven and earth. He will not let your foot slip; he who guards you will not slumber…”
2. Siddur — Blessing over the New Moon (Full Psalm)
Psalm 121 is recited in full during the monthly Kiddush Levanah (Sanctification of the New Moon) ceremony, accompanied by a Talmudic citation from Sanhedrin 42a .
3. Mishneh Torah — Fast Day Liturgy
Maimonides prescribes the recitation of four Psalms — including Psalm 121 — as part of the supplicatory prayers on a public fast day:
“He should recite the psalms, ‘I called to God in my distress and He answered me’ (Psalm 120), ‘I lift up my eyes to the mountains’ (Psalm 121), ‘Out of the depths, I called to You, O God’ (Psalm 130), ‘A prayer of the afflicted, when he becomes faint’ (Psalm 102).”
4. General Principles of Kabbalah (Ramchal)
A Kabbalistic interpretation of verse 4, connecting the “eye that does not slumber” to the Sefirah of Atik:
“The Zohar states: ‘An open eye that does not slumber; no cover, no eyelid, is upon the eye.’ And in the same connection there is a verse in the Psalms: ‘Behold he that keepeth Israel shall neither slumber nor sleep.’ (Psalm 121).”
5. Saadia Gaon — Custom for Travelers
A tradition recorded about Saadia Gaon (882–942 CE) instructs:
“One should recite certain verses (Jer. 10, 10; Gen. 49, 18) and Psalm 121 before starting on his journey.”
6. Siddur — Pidyon Ha-Ben (Redemption of the Firstborn)
The kohen’s blessing over the child incorporates language from Psalm 121:5 and 121:7 — “The Lord guards you; the Lord at your right hand is your shelter… The Lord will guard you from all evil; he will guard your life” — with footnotes explicitly citing those verses .
7. Siddur — Bedtime Shema (Footnote)
A footnote in the Bedtime Shema section references Psalm 121:4 alongside other protective verses .
Summary

The corpus contains no extended sermon or patristic homily on Psalm 121 — its presence is overwhelmingly liturgical and devotional in Jewish sources. Psalm 25, by contrast, benefits from Augustine’s full expository sermon , alongside its integration into Jewish prayer.Branch from here
Authorship, Timeframe, and Purpose — Psalm 25 and Psalm 121
Psalm 25
Authorship
The superscription explicitly attributes Psalm 25 to David. Augustine’s Latin text titles it: “TO THE END, A PSALM OF DAVID HIMSELF” . The Babylonian Talmud likewise references it as David’s composition, grouping it with his psalms when noting that “David came and reduced them to eleven principles, as it is written, A Psalm of David” .
Timeframe
The corpus contains no explicit dating for Psalm 25. The attribution to David, if taken at face value, would place it in the traditional Davidic period (roughly 10th century BCE), but the documents here offer no independent historical analysis of its composition date.
Purpose
Three layers of purpose emerge from the corpus:
- Liturgical / acrostic: Augustine’s footnote notes it is an “Alphabetical Psalm” — an acrostic structured around the Hebrew alphabet, suggesting it was crafted for memorization and liturgical use.
- Christological (Augustine): Augustine reads it as Christ speaking in the voice of the Church: “Christ speaks, but in the person of the Church: for what is said has reference rather to the Christian People turned unto God” . He interprets it as a penitential prayer of the soul turning from pride and carnal longings back to God — a plea for mercy, guidance, and forgiveness of the “offences of my youth and of my ignorance” .
- Jewish liturgical use: It is woven into the Tahanun (supplicatory prayers) in the Morning and Afternoon Services, where its language of repentance — “Remember thy mercy and thy kindness, O Lord, for they are eternal” — incorporates Psalm 25:6, among other verses . It also appears in the Musaf for festivals, quoting verses 1 and 16 as prayers for divine favor .
Psalm 121
Authorship
Psalm 121 is anonymous in its superscription. The heading reads simply “A Song of Ascents” (שִׁיר לַמַּעֲלוֹת), with no author named . This is significant because surrounding Songs of Ascents do name David:
| Psalm | Superscription |
|---|---|
| Psalm 121 | “A Song of Ascents” — no author |
| Psalm 122 | “A Song of Ascents; of David” |
| Psalm 124 | “A Song of Ascents; of David” |
| Psalm 131 | “A Song of Ascents; of David” |
The absence of David’s name on Psalm 121 stands out in this sequence. Augustine likewise titles it simply “A song of degrees” (Latin: canticum graduum), with no attribution to David .
Timeframe
As with Psalm 25, the corpus provides no explicit historical dating for Psalm 121.
Purpose
Psalm 121 belongs to the collection of 15 “Songs of Ascents” (Psalms 120–134). The corpus reveals a remarkably wide range of uses:
- Temple pilgrimage: The Mishnah records that these fifteen psalms corresponded to the fifteen steps leading from the Court of the Israelites to the Court of the Women in the Temple, where Levites would stand and sing them during the Festival of the Water-Drawing (Sukkot) . This strongly suggests they were pilgrimage songs sung by (or for) those “going up” to Jerusalem.
- Spiritual ascent (Augustine): Augustine interprets “degrees” as steps of spiritual ascent: “They who ascend… progress towards the understanding of things spiritual” . He reads the psalm as a lesson in trusting God alone — not men — as one’s keeper, since only God “shall neither slumber nor sleep” . He adds that “the Lord is thy defence upon the hand of thy right hand” refers to faith itself as the power by which believers become “sons of God” .
- Expression of trust (Siddur): The Birnbaum Siddur introduces Psalm 121 in the Sabbath Afternoon Service as “a perfect expression of trust in God, and has been on the lips of countless people when they felt the need of help beyond that which mortals can offer” .
- Monthly New Moon blessing (Kiddush Levanah): The full psalm is recited during the Sanctification of the New Moon, based on a Talmudic tradition from Sanhedrin 42a .
- Public fast days (Maimonides): The Mishneh Torah prescribes Psalm 121 among four psalms (120, 121, 130, 102) to be recited as supplicatory prayers on a public fast day .
- Travelers’ protection: A custom attributed to Saadia Gaon (882–942 CE) instructs travelers to recite Psalm 121 — along with Jeremiah 10:10 and Genesis 49:18 — before setting out on a journey .
- Redemption of the Firstborn (Pidyon Ha-Ben): Verses 5 and 7 are quoted in the kohen’s blessing over the child .
- Kabbalistic: The Zohar connects verse 4 (“He that keepeth Israel shall neither slumber nor sleep”) to the Sefirah of Atik, the divine attribute of watchfulness .
