Qui confídunt in Dómino, sicut mons Sion: non commovébitur in aeternum, qui hábitat in Jerúsalem. V. Montes in circúitu ejus, et Dóminus in circúitu pópuli sui, ex hoc nunc et usque in sáeculum. (The Tract of Laetare Sunday, Psalm 124, 1-2)
Tract They that trust in the Lord shall be as mount Sion: he shall not be moved for ever that dwelleth in Jerusalem. V. Mountains are round about it: so the Lord is round about his people from henceforth now and for ever.
As Charles Cole noted in his post yesterday, there is a particularly nice word-painting effect in this tract, in the way the notes are arranged to rise and fall on the word “mountains”, similar in spirit to the one we noted last week in the Communio of the Third Sunday of Lent.
The same text set as a very nice motet by the Slovene composer Jacob Handl (1550-91), also known as Jacobus Gallus.
