'Friend' in the Bible

Everyone has to be on guard against his friend.Don’t trust any brother,for every brother will certainly deceive,and every friend spread slander.

Each one betrays his friend;no one tells the truth.They have taught their tongues to speak lies;they wear themselves out doing wrong.

Their tongues are deadly arrows—they speak deception.With his moutha man speaks peaceably with his friend,but inwardly he sets up an ambush.

This is what each man is to say to his friend and to his brother, ‘What has the Lord answered?’ or ‘What has the Lord spoken?’
