Psalm 78:14-16

Revised Standard Version Catholic Edition

¹⁴ In the daytime he led them with a cloud,
    and all the night with a fiery light.
¹⁵ He cleft rocks in the wilderness,
    and gave them drink abundantly as from the deep.
¹⁶ He made streams come out of the rock,
    and caused waters to flow down like rivers.
