'His Right Hand' in the Bible

Now I know that the Lord saves His anointed;He will answer him from His holy heavenWith the saving strength of His right hand.

So He brought them to His holy land,To this mountain [Zion] which His right hand had acquired.

“I will also set his hand on the [Mediterranean] sea,And his right hand on the rivers [the tributaries of the Euphrates].

O sing to the Lord a new song,For He has done marvelous and wonderful things;His right hand and His holy arm have gained the victory for Him.

Appoint a wicked man against him,And let an attacker stand at his right hand [to kill him].
