'Seat' in the Bible

Now when Pharaoh had news of this, he would have put Moses to death. But Moses went in flight from Pharaoh into the land of Midian: and he took his seat by a water-spring.

And death will come to every mother's first male child in all the land of Egypt, from the child of Pharaoh on his seat of power, to the child of the servant-girl crushing the grain; and the first births of all the cattle.

And in the middle of the night the Lord sent death on every first male child in the land of Egypt, from the child of Pharaoh on his seat of power to the child of the prisoner in the prison; and the first births of all the cattle.

But Moses' hands became tired; so they put a stone under him and he took his seat on it, Aaron and Hur supporting his hands, one on one side and one on the other; so his hands were kept up without falling till the sun went down.

Now on the day after, Moses took his seat to give decisions for the people: and the people were waiting before Moses from morning till evening.
