"Gott sei gelobet und geb." (#195)

German text in the Gesangbuch:

1 Gott sei gelobet und gebenedeiet,

der uns selber hat gespeiset

mit seinem Fleische und mit seinem Blute,

das gib uns, Herr Gott, zu gute!

Kyrieleison.

Herr, durch deinen heiligen Leichnam,

der von deiner Mutter Maria kam,

und das heilige Blut

hilf uns, Herr, aus aller Noth.

Kyrieleison.

2 Der heilig Leichnam ist für uns gegeben zum Tod,

daß wir dadurch leben; nicht grüßer Güte

konnt er uns geschenken,

dabei wir sein solln gedenken.

Kyrieleison.

Herr, dein Lieb so groß dich zwungen hat,

daß dein Blut an uns groß Wunder that

und bezahlt unser Schuld,

daß uns Gott ist worden hold.

Kyrieleison.

3 Gott geb uns allen seiner Gnaden Segen,

daß wir gehn auf seinen Wegen

in rechter Lieb und brüderlicher Treue,

daß uns die Speis nicht gereue.

Kyrieleison.

Herr, dein Heilig Geist uns nimmer laß,

der uns geb zu halten rechte Maß,

daß dein arm Christenheit

leb in Fried und Einigkeit,

Kyrieleison.

Dr. M. Luther, 1524.

My prose translation:

1 May God be praised and blessed,

Who Himself has fed us

With His flesh and with His blood;

Give us that, Lord God, for [our] good!

Kyrie eleison.

Lord, by Your holy body,

Which came from Your mother Mary,

And [by] the holy blood,

Help us, Lord, out of all distress.

Kyrie eleison.

2 The holy body is given unto death for us

So that we may live by it; no greater good

Can He give us;

We should remember it.

Kyrie eleison.

Lord, Your so great love has compelled You

So that Your blood has done a great wonder for us

And pays for our guilt,

So that God is become well disposed toward us.

Kyrie eleison.

3 May God give us the blessing of all His mercy

So that we walk in His ways

In true love and brotherly loyalty,

So that the meal is not wasted on us.

Kyrie eleison.

Lord, may Your Holy Spirit never leave us,

[He] Who would grant us to maintain true moderation

So that Your poor Christendom

May live in peace and unity.

Kyrie eleison.

Dr. M. Luther, 1524.

I'm not sure, but I think "selber" in the first verse ("der uns selber hat gespeiset") is an intensive pronoun, not a reflexive pronoun acting as a direct object.

This hymn appears as "O Lord, We Praise Thee" in The Lutheran Hymnal (#313) and The Lutheran Service Book (#617) and as "O Lord, We Praise You" in Lutheran Worship (#238).  In all of these, and as the Gesangbuch notes, the text is sung to "its own tune."  Here's the TLH arrangement:

And here's an arrangement from Telemann's Fast allgemeines Evangelisch-Musicalisches Lieder-Buch:
