I will not fear
Ego obdormivi et soporatus sum, exsurrexi, quia Dominus suscepit me. Non timebo milia populi circumdantis me. Exsurge, Domine, salvum me fac, Deus meus.
I have slept and taken my rest: and I have risen up, because the Lord hath protected me. I will not fear thousands of people surrounding me: arise, O Lord; save me, O my God.
From the Waiting Psalm (Psalm 3) at Vigils, in the English rendering of the Douai Bible.
