Here is my take on it;
Moan, moan, moan; that's all that you do.
You don't understand what's the role of a Jew.
I freed you from Egypt so that you can serve me.
The way you behave I'm not sure you deserve me.
To the shore of the Red Sea I led you and guided
You doubted my power 'till the waters divided.
After singing my praises you resumed your bad mood
And moaned at the volume and taste of your food.
I said not to gather manna on Shabbat
One simple mitzvah; you can't even keep that.
And then for good measure you made a complaint
When you thought that from shortage of water you'd faint.
At Meribah I gave you a well for relief
But STILL you continue to cause me much grief.
You ungrateful lot! You sure have some neck.
You can now deal with my complaints guy, Amalek.
