Meinen Jesum laß ich nicht (I will not let go of my Jesus),[1] BWV 124, is a church cantata written by Johann Sebastian Bach.

Bach scored the work for four vocal soloists, a four-part choir and a Baroque instrumental ensemble of a horn to play the cantus firmus with the soprano, oboe d'amore, strings and basso continuo.

[2][5] The text of the hymn begins, as in the former cantata, with an idea close to the Gospel: the Christian does not want to let go of Jesus, as his parents had wished not to lose their 12-year-old boy.

[3] Bach led the Thomanerchor in the first performance of the cantata on 7 January 1725,[2][3] one day after Liebster Immanuel, Herzog der Frommen, BWV 123, for Epiphany.

[8] In the following table of the movements, the scoring, keys and time signatures are taken from Alfred Dürr's standard work Die Kantaten von Johann Sebastian Bach.

[11] A duet of soprano and alto, "Entziehe dich eilends, mein Herze, der Welt, du findest im Himmel dein wahres Vergnügen" (Withdraw yourself hurriedly, my heart, from the world, you will find in heaven your true delight),[1] is accompanied by the continuo.

[11] The cantata is closed by the final chorale stanza, "Jesum laß ich nicht von mir, geh ihm ewig an der Seiten" (I will not let go of my Jesus, I will walk beside him forever),[1] in a four-part setting.
