'Right Hand' in the Bible

and Joseph taketh them both, Ephraim in his right hand towards Israel's left, and Manasseh in his left towards Israel's right, and bringeth them nigh to him.

And Israel putteth out his right hand, and placeth it upon the head of Ephraim, who is the younger, and his left hand upon the head of Manasseh; he hath guided his hands wisely, for Manasseh is the first-born.

And Joseph seeth that his father setteth his right hand on the head of Ephraim, and it is wrong in his eyes, and he supporteth the hand of his father to turn it aside from off the head of Ephraim to the head of Manasseh;

and Joseph saith unto his father, 'Not so, my father, for this is the first-born; set thy right hand on his head.'
