'Right hand' in the Bible

Therefore you shall pay attention and be careful to do just as the Lord your God has commanded you; you shall not turn aside to the right or to the left [deviating from My commandments].

You shall act in accordance with the law which they teach you and the judgment which they tell you. You shall not turn aside from their verdict, to the right or to the left.

so that his heart will not be lifted up above his countrymen [by a false sense of self-importance and self-reliance] and that he will not turn away (deviate) from the commandment, to the right or to the left, so that he and his sons may continue [to reign] for a long time in his kingdom in Israel.

Do not turn aside from any of the words which I am commanding you today, to the right or to the left, to follow and serve other gods.

He said,“The Lord came from Sinai,And dawned on them from Seir;He shone forth from Mount Paran,And He came from among ten thousand holy ones;At His right hand was a flaming fire, a law, for them.
