If you want to avoid serious accidents in life don't swerve. "Turn not from it (don't swerve) to the right hand or to the left." Don't swerve from what?
"This book of the law shall not depart from your mouth, but you shall meditate on it day and night, so that you may be careful to do according to all that is written in it; for then you will make your way prosperous, and then you will have success." Joshua 1:8
