Es ist das Heil uns kommen her (It is our salvation come here to us), BWV 9, is a church cantata by J.S. Bach. He composed it in Leipzig for the sixth Sunday after Trinity between 1732 and 1735, based on the hymn "Es ist das Heil uns kommen her" by Paul Speratus. Bach had used already in 1716 stanza 12 of the chorale to conclude Mein Gott, wie lang, ach lange? BWV 155, in 1723 both stanza 12 and 11 to conclude the two parts of Ärgre dich, o Seele, nicht, BWV 186, and in 1724 stanza 11 to conclude Wahrlich, wahrlich, ich sage euch, BWV 86.
