My prose translation:
1 God the Father, stay with usAnd let us not perish;Make us free from all sinAnd help us to die blessedly!Preserve us from the devil;Keep us in firm faith;And let us build on You;Let us trust You from the bottom of our hearts,Wholly and completely;With all true ChristiansFleeing the devil's cunning,Getting by with the weapons of God.Amen, Amen, may that be true,So sing we: Hallelujah!2 Jesus Christ, stay with usAnd let us not perish;Make us free from all sinAnd help us to die blessedly!Preserve us from the devil;Keep us in firm faith;And let us build on You;Let us trust You from the bottom of our hearts,Wholly and completely;With all true ChristiansFleeing the devil's cunning,Getting by with the weapons of God.Amen, Amen, may that be true,So sing we: Hallelujah!3 Holy Ghost, stay with usAnd let us not perish;Make us free from all sinAnd help us to die blessedly!Preserve us from the devil;Keep us in firm faith;And let us build on You;Let us trust You from the bottom of our hearts,Wholly and completely;With all true ChristiansFleeing the devil's cunning,Getting by with the weapons of God.Amen, Amen, may that be true,So sing we: Hallelujah!Old German Petition-Litany from the 15th century."Improved and Christianly corrected" by Dr. M. Luther, 1524.
Because the original text has only a series of commas, it's sometimes difficult to distinguish between clauses. At the end of each verse especially, I'm not sure I have everything divided correctly. The line "und auf dich laß uns bauen" (And let us build on You) recalls Matthew 7:24-27, and the "Waffen Gotts" (the weapons of God) may refer to the armor of God in Ephesians 6.
This hymn appears as "God the Father, Be Our Stay" in The Lutheran Hymnal (#247), "Triune God, Oh, Be Our Stay" in Lutheran Worship (#170), and "Triune God, Be Thou Our Stay" in The Lutheran Service Book (#505). In all of these, and as the Gesangbuch notes, it's sung to "its own tune." Here's the TLH arrangement:
