O Traurigkeit in Latin

Here are two Latin stanzas I found (not translated) for O Traurigkeit [O Darkest Woe], popularly known as "Christ's Committal Hymn"; from a book on Johann Rist, here from his Himlische Lieder:

1. HEU, heu dolor,

Luctus labor!

Quis jure non queratur?

Unicus gnatus Dei

Patris—en!—humatur.

2. Deus jacet

Heu! ipsemet:

Palus dedit necatum.

Hinc polum nobis licet

Obtinere gratum.
