Psalm-like indentation

Question

I'm trying to make a kind of breviary containing psalms indented like e.g. here
What I managed so far is indenting by hand every two other verses. It goes like this:

\documentclass[12pt,a4paper,oneside]{article}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\begin{document}

\noindent O God, you are my God, for you I long; *\\
for you my soul is thirsting.\\
\indent My body pines for you *\\
\indent like a dry, weary land without water.\\
So I gaze on you in the sanctuary *\\
to see your strength and your glory.\\
\indent For your love is better than life, *\\
\indent my lips will speak your praise.\\
So I will bless you all my life, *\\
in your name I will lift up my hands.\\
\indent My soul shall be filled as with a banquet, *\\
\indent my mouth shall praise you with joy.\\
On my bed I remember you. *\\
On you I muse through the night\\
\indent for you have been my help; *\\
\indent in the shadow of your wings I rejoice.\\
My soul clings to you; *\\
your right hand holds me fast.\\
\indent Glory to the Father, and to the Son, *\\
\indent and to the Holy Spirit:\\
as it was in the beginning, is now, *\\
and will be for ever. Amen.

\end{document}

It looks fine but takes a lot of nonsense work.
Does anyone know how to automatize the job? Thanks in advance.

O God, you are my God, for you I long; *

for you my soul is thirsting.
My body pines for you *
like a dry, weary land without water.

So I gaze on you in the sanctuary *

to see your strength and your glory.
For your love is better than life, *
my lips will speak your praise.

So I will bless you all my life, *

in your name I will lift up my hands.
My soul shall be filled as with a banquet, *
my mouth shall praise you with joy.

On my bed I remember you. *

On you I muse through the night
for you have been my help; *
in the shadow of your wings I rejoice.

My soul clings to you; *

your right hand holds me fast.
Glory to the Father, and to the Son, *
and to the Holy Spirit:

as it was in the beginning, is now, *

and will be for ever. Amen.

Answer 2

Using the scripture package. Internally, this uses the same technique as David's answer, but with extra features and configuration options.

\documentclass[12pt,a4paper]{article}
\usepackage{scripture}
\scripturesetup{
  poetry/leftmargin=0pt
}
\begin{document}
\begin{scripture}
  \begin{poetry}
    O God, you are my God, for you I long; *

    for you my soul is thirsting.
    My body pines for you *
    like a dry, weary land without water.

    So I gaze on you in the sanctuary *

    to see your strength and your glory.
    For your love is better than life, *
    my lips will speak your praise.

    So I will bless you all my life, *

    in your name I will lift up my hands.
    My soul shall be filled as with a banquet, *
    my mouth shall praise you with joy.

    On my bed I remember you. *

    On you I muse through the night
    for you have been my help; *
    in the shadow of your wings I rejoice.

    My soul clings to you; *

    your right hand holds me fast.
    Glory to the Father, and to the Son, *
    and to the Holy Spirit:

    as it was in the beginning, is now, *

    and will be for ever. Amen.
