'Side' in the Bible

And behold, another beast, a second one (the Medo-Persian Empire), was like a bear, and it was raised up on one side (domain), and three ribs were in its mouth between its teeth; and it was told, ‘Arise, devour much meat.’

Then I, Daniel, looked, and behold, there stood two others, the one [angel] on this bank of the river and the other [angel] on that bank of the river.
