In exitu Israel

1 When Israel by God's command
from Pharaoh's land was bent,
And Jacob's house the strangers left,
and in the same train went:

2 In Judah God his glory shew'd,
his holiness most bright:
So did the Israelites declare
his kingdom, pow'r, and might.

3 The sea saw it and suddenly
as all amaz'd did fly,
The roaring streams of Jordan s flood
gave back immediately,

4 As rams afraid, the mountains skip'd,
their strength did them forsake;
And as the silly trembling lambs,
their tops did beat and shake.

5 What ailed thee, O sea, that thou,
so suddenly didst fly?
Ye rolling waves of Jordan's flood,
why turn'd ye so swiftly?

6 Ye mountains, ev'n as rams afraid,
why did your strength so shake?
Why did your tops as trembling lambs,
quiver with fear, and quake?

7 O earth, confess thy Sovereign Lord,
and dread his mighty hand,
Before the face of Jacob's God,
fear ye both sea and land.

8 I mean the God, who from hard rocks
causeth floods to appear,
And from the stony flint doth send
fountains of water clear.
