Our Holy Tanach via Boker tov, Boulder!:
Say tehillim (psalms)
In the wake of the ongoing captivity of IDF Cpl. Gilad Shalit in the Palestinian Authority, Rishon LeZion and Israeli Chief Rabbi Shlomo Amar has published a call for the recitation of sections from the Book of Psalms, with the prayer that the merit of the psalmist, the Biblical David, will be invoked for the sake of Shalit’s release.
Those who sow with tears will reap with song.
He will go along weeping, carrying the valuable seeds; he will come back with song, carrying his sheaves.
