Sehet, wir gehn hinauf gen Jerusalem (Behold, let us go up to Jerusalem), BWV 159, is a church cantata by Johann Sebastian Bach.
He composed it in Leipzig for the Sunday Estomihi, the last Sunday before Lent, and probably first performed it on 27 February 1729.
The gospel reading for the Sunday, from the Gospel of Luke, includes Jesus announcing his suffering and death in Jerusalem.
The cantata's theme and Bach's music foreshadow his Passion.
