I can't figure out constraints to save my life

I'm a maya animator trying to learn blender (I initially picked up maya because of school). So I have been working on a shot where I want my character to hold a sword with 2 hands and swing it around. Normally, I would rig the sword to one hand and the other hand to the sword. However, I can't even get the sword to parent onto one of the hands.
