O Lord, look unto my aid; let them be confounded and ashamed, who seek after my soul to take it away. O Lord, look unto my aid. (The Offertory of the Sixteenth Sunday after Pentecost.)
Offertorium, Ps. 39 Dómine, in auxilium meum réspice: confundantur et revereantur, qui quaerunt ánimam meam, ut áuferant eam. Dómine, in auxilium meum réspice.This Offertory is also sung on Friday of the second week of Lent; when I went to search for it on YouTube, this very beautiful polyphonic version written for that season also came up. No information is given about who composed it; if any one knows, please be so kind as to leave a message in the combox.
