'Straight' in the Bible

Be my guide, O Lord, in the ways of your righteousness, because of those who are against me; make your way straight before my face.

He who is holy will see that you are holy; but to the man whose way is not straight you will be a hard judge.

God puts a strong band about me, guiding me in a straight way.

Because of it I keep straight in all things by your orders; and I am a hater of every false way.
