'Right Hand' in the Bible

Is not the entire land before you? Please separate [yourself] from me. If you take the left, then I will go to the right; or if you choose the right, then I will go to the left.”

And as her soul was departing, (for she died), she named him Ben-oni (son of my sorrow); but his father called him Benjamin (son of the right hand).

Then Joseph took them both, Ephraim with his right hand toward Israel’s left, and Manasseh with his left hand toward Israel’s right, and brought them close to him.

But Israel reached out his right hand and laid it on the head of Ephraim, who was the younger, and his left hand on Manasseh’s head, crossing his hands [intentionally], even though Manasseh was the firstborn.

When Joseph saw that his father laid his right hand on Ephraim’s head, it displeased him [because he was not the firstborn]; and he grasped his father’s hand to move it from Ephraim’s head to Manasseh’s head.

Joseph said to his father, “Not so, my father, for this is the firstborn; place your right hand on Manasseh’s head.”
