When thou didst terrible things which we looked not for, thou camest down, the mountains quaked at thy presence.

When You did awesome works that we did not expect, You came down, and the mountains trembled at Your presence.

In Thy doing fearful things--we expect not, Thou didst come down, From Thy presence did mountains flow.

When thou didst terrible things [which] we looked not for, thou camest down, and the mountains flowed down at thy presence.
