"...Be merciful unto me according to thy word" 1t dtg. "Tih-tuhn"
Left hand? Index finger... UP!
Right hand? "Tih". Little, ring, and index fingers down, thumb out; and middle finger resting OUTSIDE of thumb muscle, but still pulled down so that we are not inadvertently giving anyone the middle finger!
P.S. Sorry! Here I was so convinced I had that right! If simply tells me I certainly am not done learning this Psalm!
