Proverbs 17:18

One who lacks sense gives a pledge

and puts up security in the presence of his neighbor.

One without sense enters an agreement

and puts up security for his friend.

It’s poor judgment to guarantee another person’s debt

or put up security for a friend.

A person who lacks sense pledges;

he becomes security before his neighbor.

A man void of understanding striketh hands,

And becometh surety in the presence of his friend.
