'Hand' in the Bible

would ye therefore tarry till they were grown? would ye therefore stay from having husbands? nay, my daughters, for it grieveth me much for your sakes, for the hand of Jehovah is gone forth against me.

Then said Boaz, What day thou buyest the field of the hand of Naomi, thou must buy it also of Ruth the Moabitess, the wife of the dead, to raise up the name of the dead upon his inheritance.

And Boaz said unto the elders, and unto all the people, Ye are witnesses this day, that I have bought all that was Elimelech's, and all that was Chilion's and Mahlon's, of the hand of Naomi.
