'Left' in the Bible

Is not all the land before you? then let us go our separate ways: if you go to the left, I will go to the right; or if you take the right, I will go to the left.

Then taking Ephraim with his right hand, Joseph put him at Israel's left side, and with his left hand he put Manasseh at Israel's right side, placing them near him.

And Israel, stretching out his right hand, put it on the head of Ephraim, the younger, and his left hand on the head of Manasseh, crossing his hands on purpose, for Manasseh was the older.
