We Hung Up Our Lyres

Psalm 137:1-2

By the waters of Babylon,
    there we sat down and wept,
    when we remembered Zion.
2 On the willows there
    we hung up our lyres.
3 For there our captors
    required of us songs,
and our tormentors, mirth, saying,
    “Sing us one of the songs of Zion!”

Many singers and musicians from the desdendants of Asaph were carried off as captives to Babylon.  Ezra 2 records for us the list of men who returned to Jerusalem from the exile.  The list of men of Israel included the musicians, the descendants of Asaph.  (Ezra 2:41) 

Lyres were musical instruments that Levites used in the temple service to worship God.

Notice, they did not hide their lyres and harps.
They did not put away their lyres and harps under their beds.

They hung them up on the willows.
There was no song to sing.

My Beloved, can you feel their heart beat?

They were so broken hearted when they remembered Zion!
No song to sing.
