Rabbosai Nevareich!By Rabbi Jack Abramowitz
This “song of ascents” is no doubt the most famous one in the series, as it is the Shir HaMaalos we say before bentching on Shabbos and Yom Tov.
David says that when G-d brought the exiles back to Israel, they were like dreamers. Their mouths were filled with laughter and their tongues with song. The nations of the world will acknowledge that G-d has done great things for the Jewish people. The Jews respond, “Yes, G-d HAS done great things with us; that’s why we’re so happy!”
All of this speaks of the future redemption. David asks G-d to return the captives from exile, invigorating them like streams do a dry land. Those who sow in tears will reap in joy; the person who carried seed while crying will return home carrying sheaves in joy.
