'Risk' in the Bible

"Give me 12,000 men! I'll leave tonight and pursue David," Ahithophel advised Absalom.

If I had acted at risk of my own life -- and nothing is hidden from the king! -- you would have abandoned me."

And he said, Be it far from me, Jehovah, that I should do this thing! is it not the blood of the men that went at the risk of their lives? Therefore he would not drink it. These things did the three mighty men.
