Psalmus 90, 1–8 (Vulgate)
90:1 Qui habitat in adjutorio Altissimi, in protectione Dei cæli commorabitur.
2 Dicet Domino: Susceptor meus es tu et refugium meum; Deus meus, sperabo in eum.
3 Quoniam ipse liberavit me de laqueo venantium, et a verbo aspero.
4 Scapulis suis obumbrabit tibi, et sub pennis ejus sperabis.
5 Scuto circumdabit te veritas ejus: non timebis a timore nocturno;
6 a sagitta volante in die, a negotio perambulante in tenebris, ab incursu, et dæmonio meridiano.
7 Cadent a latere tuo mille, et decem millia a dextris tuis; ad te autem non appropinquabit.
8 Verumtamen oculis tuis considerabis et retributionem peccatorum videbis.
Psalm 91, 1–8 (King James Version)
91:1 He that dwelleth in the secret place of the most High shall abide under the shadow of the Almighty.
2 I will say of the Lord, He is my refuge and my fortress: my God; in him will I trust.
3 Surely he shall deliver thee from the snare of the fowler, and from the noisome pestilence.
4 He shall cover thee with his feathers, and under his wings shalt thou trust: his truth shall be thy shield and buckler.
5 Thou shalt not be afraid for the terror by night; nor for the arrow that flieth by day;
6 Nor for the pestilence that walketh in darkness; nor for the destruction that wasteth at noonday.
7 A thousand shall fall at thy side, and ten thousand at thy right hand; but it shall not come nigh thee.
8 Only with thine eyes shalt thou behold and see the reward of the wicked.
