Psalm 137: How shall we sing the Lord's song while in a strange land?

Psalm 137

¹By the rivers of Babylon, there we sat down, yea, we wept,
      when we remembered Zion.
²We hanged our harps
      upon the willows in the midst thereof.
³For there they that carried us away captive required of us a song;
      and they that wasted us required of us mirth,
      saying, Sing us one of the songs of Zion.

⁴How shall we sing the LORD's song
      in a strange land?
⁵If I forget thee, O Jerusalem,
      let my right hand forget her cunning.
⁶If I do not remember thee,
      let my tongue cleave to the roof of my mouth;
if I prefer not Jerusalem above
      my chief joy.

⁷Remember, O Lord, the children of Edom in the day of Jerusalem;
      who said, Rase it, rase it, even to the foundation thereof.
⁸O daughter of Babylon, who art to be destroyed;
      happy shall he be, that rewardeth thee as thou hast served us.
⁹Happy shall he be, that taketh
      and dasheth thy little ones against the stones.

The setting for Psalm 137 is Babylon after they had taken the Israelites captive out of the homeland.  How could the Isrealites sing for Babylonians the song(s) of our Lord?   They have brought so much pain and suffering to the Israelites.  Some scholars point out that those who are happy at calamities, especially the calamities of Israel, shall not go on unpunished.  However, I believe in these situations we shall hope for God to intercede.  For in the Lord's prayer we learn that we cannot be forgiven unless we first forgive others.  We must remember that Jesus died for the forgive of us our sins - he paid the ultimate price for us.  So, as hard as it may seem, when people trespass against we must forgive them.

Lord, our father in heaven.  Hallowed be thy name.  Thy Kingdom come.  Thy will be done, on earth as it is in Heaven. Give us today our daily bread.  Forgives us our trespasses, as we forgive those who trespass against us.  Lead us us not into temptation, but deliver us from evil.  For thine is the power and the glory forever.

For if we give those who sin against us - your heavenly Father will also forgive you.  Amen
