'Shaking' in the Bible

And a great number of the people had gone over Jordan to the land of Gad and Gilead; but Saul was still in Gilgal, and all the people went after him shaking in fear.

And there was great fear in the tents and in the field and among all the men of the armed force, and the attackers were shaking with fear; even the earth was moved with a great shaking and there was a fear as from God.

Then Samuel said, Make Agag, the king of the Amalekites, come here to me. And Agag came to him shaking with fear. And Agag said, Truly the pain of death is past.
