Wilt heden nu treden voor God, den Heere, / Hem boven al loven van harte zeer.
Our renderingLet us now step before God the Lord, and praise him above all things with a full heart.
What it is
Published posthumously in 1626 by Valerius's heirs in Veere, Zeeland—a city that William the Silent had acquired as part of the marquisate of Veere and Vlissingen in 1582, placing it firmly in Orange territory. This collection of 72 patriotic and devotional songs narrates the history of the Dutch struggle for independence within an explicitly providential Reformed theological framework. Its most famous pieces—the Wilhelmus, 'Wilt heden nu treden' (We Gather Together), and 'Merck toch hoe sterck'—linked the Reformed faith explicitly to the House of Orange as God's chosen instrument for Dutch liberty. Valerius's arrangement of the Wilhelmus gave it the slow, solemn, devotional form used in worship today.
Why it still matters
'Wilt heden nu treden' (We Gather Together) from this collection is still sung at Thanksgiving and Reformed services worldwide; the full collection remains a treasury of Dutch Reformed devotional hymnody and can be used for seasonal or patriotic worship occasions.

Wilhelmus van Nassouwe (The Wilhelmus)
Wilhelmus van Nassouwe
The 15-stanza hymn whose acrostic spells 'Willem van Nassov,' composed in the voice of William the Silent as a first-person confession of faith and loyalty to God above earthly rulers. Marnix, William's personal secretary, is the traditional attributed author, but authorship remains actively disputed: a 2016 computational stylometric analysis attributed the text to Petrus Datheen rather than Marnix, and the scholarly consensus treats authorship as unresolved. The text fuses the psalmic idiom with Reformed theology, expressing personal dependence on God in the midst of political and military danger. The Valerius edition (1626) gave the hymn the slow, solemn musical setting it retains today as the world's oldest national anthem.
De Psalmen Davids ende andere lofsanghen (Datheen's Psalter)
De Psalmen Davids ende andere lofsanghen
The foundational metrical psalter of Dutch Reformed worship, Datheen translated the 1562 Genevan Psalter (Marot/Beza texts, Bourgeois melodies) into Dutch, binding it together with the Heidelberg Catechism and liturgical formularies as a single church handbook. The Convent of Wesel (1568) mandated it throughout all Netherlands churches, and successive synods (1574, 1578, 1618) continued to require its use. It remained the official sung psalter of the Dutch Reformed church until 1773, meaning every Orange-Nassau stadhouder from William the Silent through William III worshipped and sang from this book across multiple generations. Datheen had complex relations with William the Silent—he opposed the prince's irenic religious policy—yet the psalter he produced became the sonic fabric of Orange-Nassau court chapel and household devotion.
Genevan Psalter (Pseaumes de David / Psaumes mis en rime françoise)
The complete 150-psalm psalter completed under Calvin's direction in Geneva in 1562, with metrical French texts by Marot and Beza set to tunes primarily by Loys Bourgeois, and the direct source from which Datheen's Dutch psalter was translated. William the Silent was a French-speaking prince and Marnix van Sint-Aldegonde—his closest advisor and the translator of the Dutch psalter—studied directly under Calvin and Beza in Geneva, making familiarity with the French psalter highly probable in Francophone Orange circles. The Genevan tunes passed wholesale into the Dutch Reformed church and remain the melodic backbone of Dutch Reformed psalmody to the present day. Court worship in the bilingual Orange household plausibly drew on both the French original and the Dutch translation, though no document specifically records French psalter use in the Orange court chapel.
