My heart is fixed, O God, I'll sing and with my glory praise

1 My heart is fixed, O God; I'll sing,
and with my glory praise.
2 Awake up psaltery and harp;
myself I'll early raise.
3 I'll praise thee 'mong the people, Lord;
'mong nations sing will I:
4 for above heaven they mercy's great,
thy truth doth reach the sky.

5 Be thou above the heavens, O God,
exalted gloriously,
thy glory all the earth above
be lifted up on high.
6 That those who thy beloved are
delivered may be,
O do thou save with thy right hand,
and answer give to me.

7 God in his holiness did speak,
My joy shall be complete;
Shechem I will divide, by line
the vale of Succoth mete.
8 Gilead I claim as mine by right;
Manasseh mine shall be,
Ephraim is of my head the strength,
Judah gives laws for me;

9 Moab my wash-pot is; my shoe
I'll over Edom throw;
over Philistia my shout
of triumph forth shall go.
10 O who is he will bring me to
the city fortified?
O who is he that to the land
of Edom will me guide?

11 O God, who hast rejected us,
wilt thou not help us so?
Even thou, O God, who dost no more
forth with our armies go.
12 From trouble help thou us, for vain
the help from man that flows.
13 Through God we shall do valiantly;
he shall tread down our foes.
