1 When Isra'l, freed from Pharaoh’s hand,
Left the proud tyrant and his land,
The tribes with cheerful homage own
Their king and Judah was his throne.
2 Across the deep their journey lay;
The deep divides to make them way;
Jordan beheld their march, and fled
With backward current to his head.
3 The mountains shook like frighted sheep,
Like lambs the little hillocks leap!
Not Sinai on her base could stand,
Conscious of sov'reign power at hand.
4 What pow'r could make the deep divide?
Make Jordan backward roll his tide?
Why did ye leap, ye little hills
And whence the fright that Sinai feels?
5 Let ev'ry mountain, ev'ry flood,
Retire and know the approaching God,
The King of Israel: see Him here;
Tremble, thou earth, adore and fear.
6 He thunders, and all nature mourns,
The rock to standing pools he turns;
Flints spring with fountains at his word,
And fires and seas confess the Lord.
