'Straight' in the Bible

Their legs were straight and the soles of their feet were like a calf’s hoof, and they sparkled and gleamed like shiny 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 another. Every living being had two wings which covered its body on one side and on the other side.

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 forward.

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 through which he entered, but shall go out straight ahead [through the opposite gate].
