Hebrew??

Tonight is a Thursday night and my second Millennial choir practice.  My first practice was last week.
OMGosh...
I sing - I have since I was young.  And I'm a good singer.  I can read most music - I can pick out my part and any other part, usually.
But last week??  I was humbled and put in my place.  It was hard....really hard.  There were a few of the songs that were pretty easy to read and learn my part fairly quickly.  But then, there were two or three songs that I thought, 'You have got to be kidding me.'  I couldn't even FIND my part, let alone sing it.  The rhythms were horrendous, the tempo so fast - and the words?  The words were in HEBREW!!!  How am I supposed to learn Hebrew AND sing a song that makes absolutely no melodic sense what so ever???  The Hebrew one is long too - carries no consistency to it, isn't even pretty and doesn't make any sense.  How am I supposed to LEARN that???
It stretches me right out of my comfort zone.  Hard.  I wasn't looking for hard.  I was looking for pretty, easy and sharing my talent.  I wasn't looking for 'You've got to be freakin' kidding me!!!'
I think it may be time to drop to my knees and ask for divine help.  I've never been challenged musically before.  I've never felt 'out of my league' musically...but I'm feeling overwhelmed.
We were advised to keep faith and to not give up too early on this.  I'm going to have to trust Brett (the conductor), that he knows what he's doing.
Cuz, I don't.
