Psalms 41:9

41:9 Even my close friend whom I trusted,

he who shared meals with me, has turned against me.

Psalms 55:12-14

55:12 Indeed, it is not an enemy who insults me,

or else I could bear it;

it is not one who hates me who arrogantly taunts me,

or else I could hide from him.

55:13 But it is you, a man like me,

my close friend in whom I confided.

55:14 We would share personal thoughts with each other;

in God’s temple we would walk together among the crowd.

Psalms 55:20

55:20 He attacks his friends;

he breaks his solemn promises to them.
