'Security' in the Bible

So your servant said, 'May the word of my lord the king be my security, for my lord the king is like the angel of God when it comes to deciding between right and wrong! May the Lord your God be with you!'"

He threw rocks at David and all of David's staff who were accompanying him, while all the rest of the entourage, including all of David's security detail, were close by him.

He was well known among the platoons, but he didn't measure up to the Three. David placed him in charge of his security detail.
