Until fairly recently music scholars believed that this setting of the sixth verse from Psalm six was was Weelkes' only Latin motet. It's a penitential motet whose structure owes much to Thomas Morley's setting of the same text. Thus you can hear several motifs in each phrase of the text. The result is an impressively expansive piece of music that makes very telling use of dissonance. It's sung to great effect below by the Tewkesbury Abbey Schola Cantorum directed by Benjamin Nicholas.
