'Straight' in the Bible

Their legs were straight and their feet were like a calf’s hoof, and they gleamed like burnished bronze.

their wings touched one another; their faces did not turn when they moved, each went straight forward.

And each went straight forward; wherever the spirit was about to go, they would go, without turning as they went.

Under the expanse their wings were stretched out straight, one toward the other; each one also had two wings covering its body on the one side and on the other.

As for the likeness of their faces, they were the same faces whose appearance I had seen by the river Chebar. Each one went straight ahead.

But when the people of the land come before the Lord at the appointed feasts, he who enters by way of the north gate to worship shall go out by way of the south gate. And he who enters by way of the south gate shall go out by way of the north gate. No one shall return by way of the gate by which he entered but shall go straight out.
