One of the classic Israeli songs. Surprised it hasn't made it's way to Mudcat before.
In the mid 1930s, a propoganda film called "LeChaim Chadashim" was made about pioneering Israel. A song was needed, so they asked the poet and lyricist Nathan Alterman to write the lyrics. The music was composed by Daniel Sambursky, a recent immigrant from Germany. He was one of the first to realise the danger posed by the Nazis.
The song Alterman and Sambursky came up with was called Shir HaEmek, the Valley Song. Sambursky performed the song along with members of Kibbutz Givat Brenner.
The valley is the Jezreel. Beit Alfa and Nahalal are settlements in the valley.
The original 'clip' can be watched here. It starts at around 4:20. The earlier bit is a different song by Sambursky. He was featured in an old Israeli TV prog.

Here is a more recent performance, though I was surprised to find that the singers were really Israeli.

Shir HaEmek

Chorus:
Ma, ma laila mileil?

Chorus


The Valley Song

Rest has come to the weary
and calm to the toiler.
A pale night unfolds
over the fields of the Jezreel Valley.
Dew below and a moon above
from Beit Alfa to Nahalal.

Chorus:
What, what from night to night?
Silence in the Jezreel.
Slumber valley, wondrous land,
we are your guard.

The sea of grain sways,
the song of the herd rings out,
this is my land and her fields,
this is the Jezreel Valley.
Blessed be my land and gloried
from Beit Alfa to Nahalal.

Chorus

Gloom on Mount Gilboa,
a horse gallops from shade to shade.
A cry rises high,
from the fields of the Jezreel Valley.
Who fired and who fell
between Beit Alfa and Nahalal?

Chorus.
