Psalm 31: 2,3,1 [Latin] – Be my protector and place of refuge, to keep me safe; for you are my strength and refuge; and for the sake of your name, you will lead and nourish me.

In you O Lord, I have put my trust; do not let me be put to shame; In your justice rescue me.

Esto mihi in Deum protectorem, et in locum refugii, ut salvum me facias: quoniam firmamentum meum, et refugium meum es tu: et propter nomen tuum dux mihi eris, et enutries me.

V. In te, Domine, speravi, non confundar in aeternum: in justitia tua libera me, et eripe me.
